Congratulations! You just received your permanent implant prosthesis — the final step in a process that can last a lifetime if you care for it correctly. This guide explains everything you need to know to keep your new prosthesis in perfect condition for decades.

What is an implant prosthesis?

An implant prosthesis is the artificial restoration (tooth, teeth or full denture) fixed onto one or more already-osseointegrated titanium implants. It is the final stage of implant treatment — the implant was the root, and the prosthesis is the visible tooth.

Type of prosthesis you received:

Single crown on implant · Single tooth: A single porcelain, zirconia or metal-ceramic tooth screwed or cemented onto an abutment that fits the implant. The most common option for replacing an individual tooth.
Bridge on implants · Several teeth: Two or more joined crowns supported on one or more implants. Replaces several adjacent teeth without needing one implant per tooth.
Overdenture (removable implant prosthesis) · Removable: Full or partial denture held with retention attachments to the implants. The patient can remove it for cleaning but has much greater stability than a conventional denture.
Fixed complete prosthesis (All-on-4 / All-on-6) · Full arch: Complete fixed denture on 4-6 implants. Cannot be removed. Replaces all teeth in one arch with high stability and function.

How is your prosthesis fixed?

Screw-retained · Preferred: A screw holds it to the implant from above. It has a small access hole covered with composite. Most recommended because it can be removed for adjustments or repairs.
Cement-retained: Fixed with dental cement over the implant abutment, just like a crown on a natural tooth. Cannot be easily removed. Very good aesthetics with no visible hole.

The implant prosthesis is not the implant itself. The implant (the titanium screw in the bone) is already permanently fixed. The prosthesis may need maintenance, adjustments or replacement over time.

The First Days with Your Prosthesis

A new stage that requires adaptation

Bite may feel different: It is completely normal for the bite to feel different — higher, different or strange during the first days. Your mouth and muscles need time to adapt to the new geometry. If after 7-10 days you feel a very marked pressure point when closing, let us know for an adjustment.
Tongue will constantly explore: The tongue will instinctively seek the new prosthesis. This ‘foreign body’ sensation disappears within days as the brain integrates the new geometry as its own.
Small change in speech: Especially with front prostheses or complete prostheses, there may be a slight change in pronunciation of certain letters. Normalizes within days with natural speech practice.
Sensitivity in surrounding gum: The gum and tissues around the abutment may be slightly sensitive the first days — normal response to prosthesis fitting. If sensitivity is intense or doesn’t improve in a week, let us know.
There should be no pain · Important: Unlike implant surgery, placing the permanent prosthesis should NOT cause pain. Adaptation discomfort yes — pain NO. If there’s pain when biting or in the gum, contact us.

Implant Prosthesis Hygiene

The most important factor for it to last decades

Peri-implantitis — the bacterial infection around the implant — is the most common cause of late implant failure. It is silent, progressive and can destroy bone around the implant without you feeling pain until it’s too late. Perfect hygiene is the only effective prevention.

Why is implant hygiene different from natural tooth hygiene?

	Natural tooth	Implant
Bone attachment	Natural tooth has periodontal ligament — a fiber network acting as shock absorber with defense capability	Implant has direct osseointegration — no ligament, no shock absorber, less bacterial defense capacity
Warning signals	Ligament transmits early pain with infection	Peri-implantitis can progress without pain until advanced stages
Repair	Natural tooth can regenerate some tissue with mild inflammation	Bone lost around the implant is very difficult to recover

Your hygiene routine with implant prosthesis:

Brushing 2-3 times daily — especially before bed · essential: Brush the implant crown like any other tooth with soft bristles. Pay special attention to the margin between crown and gum — the most vulnerable area. Gentle circular motions at 45°. Electric toothbrush is ideal for implants.
Dental floss or Super Floss — daily, without exception · essential: Pass floss under the implant crown to the gum line. Super Floss (floss with spongy section) or threaders allow passing floss under the crown contour. Also clean the space between the implant crown and adjacent teeth. No excuse to skip flossing.
Interdental brush (proxy brush) · essential: The appropriately sized interdental brush (your dentist tells you which) is very effective for cleaning around the implant abutment, under the crown contour and in the spaces between teeth. Use it after regular brushing.
Water flosser (Waterpik) — highly recommended · highly recommended: The water flosser cleans the peri-implant sulcus — the space between gum and implant where biofilm causing peri-implantitis accumulates. Aim at medium pressure directly at that sulcus. Doesn’t replace flossing but complements it very effectively.
Periodic antiseptic rinse · recommended: A 0.05-0.12% chlorhexidine or fluoride rinse before bed is an additional layer of protection. Especially useful if you tend to accumulate plaque or had periodontitis. Not for indefinite daily use — ask your dentist about frequency.

If your prosthesis is removable (overdenture):

Remove it after each main meal to clean the implants and prosthesis
Clean implants and their retention attachments with a soft brush and floss
Clean the removed prosthesis with a special denture brush — without abrasive toothpaste that scratches the acrylic
Soak prosthesis in denture cleaning solution (not hot water — deforms acrylic)
Sleep without prosthesis or as your dentist indicates — allows gum and implants to rest
Store prosthesis in clean cold water when not in use to prevent drying and deforming

Eating with Implant Prosthesis

Adaptation the first days and permanent habits

First 5-7 days of adaptation:

Eat on the opposite side if there’s sensitivity in the implant area
Preferably soft foods while adapting to the new bite
Moderate temperature the first 48 hours if sensitive
Chew slowly — allows muscles to adapt to the new occlusion

Permanent habits to protect the prosthesis:

Biting non-food objects: Pens, pencils, nails, bottle caps. Torsional forces can fracture porcelain or loosen the prosthesis screw. — high
Chewing ice: Ice hardness can fracture ceramics even from the most resistant materials. — high
Opening things with your teeth: Packages, bottles, tags. Lateral forces are especially damaging to implants. — high
Very hard and sticky foods frequently: Hard candies, bones, very hard bread. Prosthesis can fracture. Sticky candies can loosen the screw. — medium
Untreated bruxism: Grinding generates forces that can fracture ceramics, loosen the abutment screw or damage the implant long-term. — very high

No restriction

Well-cooked meats cut normally
Fresh fruits and vegetables in normal pieces
Bread and moderately crunchy foods
Practically any food — prosthesis designed for normal chewing

Professional Maintenance

Indispensable for the implant to last a lifetime

Regular professional maintenance is NOT optional with implants. Peri-implantitis detected early is treatable. Detected late it can mean losing the implant. Your implant investment is protected with regular check-ups.

Check-ups every 6 months (or every 3-4 months with risk factors):

Clinical evaluation of gum condition around the implant
Peri-implant probing to detect pockets or inflammation
Periodic X-ray to monitor bone levels
Professional cleaning with special implant instruments
Screw torque verification (screw-retained prostheses)
Evaluation of ceramic condition and crown edges
Prosthesis polishing to remove stains and deposits

Professional cleaning with special instruments

Implants CANNOT be cleaned with the same metal instruments used on natural teeth — metal can scratch the titanium and abutment surface, favoring bacterial adhesion. We use plastic, teflon, carbon or special implant ultrasound instruments. Always inform the hygienist you have implants.

Prosthesis screw check

In screw-retained prostheses, the screw fixing the crown to the implant can loosen over time from chewing forces. At each check-up we verify and re-tighten the screw if necessary. If you feel the prosthesis ‘loose’ or moving between visits, let us know.

Lifespan and What to Expect Long-Term

The implant can last a lifetime — the prosthesis may need maintenance

The titanium implant:

With good hygiene, regular maintenance and without risk factors like smoking, the implant can last decades — literally a lifetime. Titanium doesn’t wear down, doesn’t decay and is inert to the body.

The prosthesis (crown/bridge/denture):

Zirconia crown: 15-25 years — Most fracture-resistant
All-porcelain crown: 10-15 years — Can fracture with intense forces
Metal-ceramic crown: 15-20 years — High durability on molars
Overdenture (acrylic): 5-8 years — Acrylic wears and needs relining

These are estimates with good hygiene and no bruxism. Untreated bruxism can fracture any ceramic material within 2-5 years.

What may need maintenance?

Re-torquing or replacing the prosthesis screw (every 1-3 years)
Relining overdentures as bone changes over time
Replacing overdenture retention attachments (every 1-2 years)
Repair or replacement of crown if fractured
Bite adjustment if adjacent natural teeth shift

What the implant does NOT need:

Root canals — the implant has no nerve
Fillings or composite — titanium doesn’t decay
Special cavity prevention care
As many interventions as a natural tooth

Bruxism and Implants — A Risky Combination

If you grind or clench your teeth, this directly affects you

Bruxism (grinding or clenching teeth) is the most important risk factor for implant prosthesis fracture. Forces generated during bruxism can be 5-6 times greater than normal chewing. The implant itself can withstand these forces, but the prosthesis ceramic can fracture.

The custom night guard — most effective protection

If you have bruxism, wearing a custom-made occlusal guard every night is the best investment you can make to extend prosthesis life. The guard distributes forces and absorbs impact before it reaches the ceramic. A guard can protect a much more expensive prosthesis.

Signs you may have bruxism:

You wake up with jaw or temporal muscle pain
Your partner tells you that you grind your teeth in sleep
You have visible wear on natural teeth
You have frequent morning headaches
Prosthesis ceramic has fractured before without apparent cause

Factors Affecting Implant Life

What you do in daily life matters

Tobacco — still the greatest risk · Important: Tobacco not only affects initial osseointegration — it also increases peri-implantitis risk once the prosthesis is in function. Smokers lose implants more frequently even years after placement. If you smoke, it’s essential you know this.
Diabetes — strict glycemic control: Poorly controlled diabetes reduces the body’s ability to fight peri-implant infection. Diabetic patients with well-controlled HbA1c have success rates similar to non-diabetics. Glycemic control protects the implant.
Certain medications: Bisphosphonates (for osteoporosis), immunosuppressants and head-neck radiotherapy can affect implant life. If any doctor prescribes a new treatment, let us know to assess the impact.
Hygiene — the most controllable factor: Of all factors, hygiene is what you can control most. Patients with impeccable hygiene and regular maintenance rarely lose implants. Peri-implantitis is almost completely preventable with hygiene.

Warning Signs

When to contact us — acting early protects the implant

Contact the clinic if you experience:

Prosthesis feels loose or moves: If the crown, bridge or prosthesis moves when biting or when touched with tongue, the screw may have loosened or cement failed. Let us know to re-tighten or re-cement. Don’t eat with a loose prosthesis — you may swallow the screw.
Pain when biting or pressing the implant: The implant shouldn’t hurt during normal function. Pain when biting may indicate peri-implantitis, component fracture or screw problem. Requires evaluation.
Inflamed, red or bleeding gum around implant: Healthy mucosa around the implant is firm and pink. Inflammation, redness or bleeding upon probing are early signs of mucositis (reversible inflammation) or peri-implantitis. Early detection saves the implant.
Prosthesis fractured or has irregular edge: A fractured porcelain fragment can have sharp edges that injure the tongue. The prosthesis also stops protecting the implant well. Need to evaluate repair or replacement.
Persistent bad taste or discharge in area: May indicate active peri-implant infection. A metallic, salty or unpleasant taste in the implant area that doesn’t go away requires urgent evaluation.
The implant itself moves when touched directly: If you perceive the implant itself (not just the prosthesis) has mobility, there may be osseointegration failure or severe peri-implantitis. Requires urgent attention.

This is completely normal:

Different bite the first 3-7 days
Slightly sensitive gum first days near the abutment
Small temporary change in pronunciation
Tongue constantly exploring the prosthesis at first
Mild change in chewing sensation — no pain

Frequently Asked Questions

Can the implant prosthesis fall off or come loose?

Screw-retained prostheses can loosen if the screw loses torque — relatively infrequent but it happens. Fixed by re-tightening the screw at the clinic, a simple operation. Cement-retained prostheses rarely come loose. If you feel movement, let us know immediately.

Do I need to do anything special when brushing the prosthesis?

Yes: brush the margin between crown and gum with special attention, use dental floss or Super Floss daily and complement with water flosser. The difference from a natural tooth is that the space under the implant crown needs cleaning with specific technique — the dentist or hygienist will show you how.

Can the implant prosthesis get a cavity?

The prosthesis itself (porcelain, zirconia, metal) can’t decay. But if there are adjacent natural teeth or if the abutment has any material-interface, there could be risk there. Regular maintenance detects any problem.

How long does the prosthesis last?

The implant can last a lifetime. The prosthesis above has variable lifespan: zirconia crowns 15-25 years, metal-ceramic 15-20 years, acrylic overdentures 5-8 years. With good hygiene and no bruxism, many prostheses last longer than estimated.

Can I eat everything with the prosthesis?

Practically yes. The prosthesis is designed for normal chewing function. Only avoid extremes: ice, very hard candies, biting non-food objects. After the first adaptation days, enjoy completely normal eating.

Do I need more frequent dental check-ups than before the implant?

Yes. With implants, check-up is recommended every 6 months minimum (vs. once a year or more for natural teeth in low-risk patients). If you smoke, have diabetes or history of periodontitis, every 3-4 months. The implant is protected with regular maintenance.

Does the implant prosthesis look different from a natural tooth?

With current materials (zirconia, porcelain), the crown on implant is practically indistinguishable from a natural tooth to the naked eye. In some cases the gum margin may look slightly different — the aesthetic dentist can optimize this aspect.

What if I need an MRI or surgery?

Titanium implants are safe for MRIs — not ferromagnetic and don’t interfere. For surgeries or other medical procedures, always inform your doctors you have dental implants, especially if it involves general anesthesia or bone-affecting medications.

Can I whiten my teeth with an implant?

Whitening doesn’t change the color of the implant prosthesis — ceramic material doesn’t respond to peroxide. Whitening natural teeth may create a color difference with the implant prosthesis. If you want to whiten, consult your dentist first.

What do I do if the implant fails?

If advanced peri-implantitis or failure occurs, the implant is removed. After a bone recovery period (generally 3-6 months), the possibility of placing a new implant is evaluated. Not all cases are candidates for reimplantation, but many are. It’s not the end — consult your dentist.
