Complete guide for your invisible orthodontic treatment success. Learn how to care for your aligners and get the best results.
What are clear aligners?
Clear aligners (like Invisalign®) are custom-made removable trays that gradually move your teeth. Unlike traditional braces, you can remove them to eat and brush your teeth.
What are attachments?
They are small tooth-colored resin buttons temporarily bonded to some teeth. They help the aligner make more precise movements. They’re almost invisible and are removed at the end of treatment.
The great advantage of aligners is their discretion and comfort, but they require discipline and commitment on your part to work properly.
The 22-Hour Rule
This is the most important rule of your entire treatment
You must wear your aligners at least 22 hours per day
You only have 2 hours per day for eating and brushing
What happens if I don’t meet the 22 hours?
- Teeth don’t move as they should
- The next aligner won’t fit properly
- Treatment takes longer (extra months)
- Additional aligners may be needed (extra cost)
- In severe cases, treatment must restart
Tips to meet the 22 hours
- Eat at set times, don’t snack
- Reduce the time of each meal
- Always carry your case with you
- Set alarms if you forget to put them back
- Don’t remove them “just for a bit” - it adds up
Do the math: 22 hours = 3 meals of 30-40 minutes each. If you remove them longer, you’re not meeting the requirement.
Your Daily Routine with Aligners
Follow these steps every time you eat
- 1. Remove the aligners: Wash your hands first. Remove from the back teeth forward, carefully to avoid damage.
- 2. Store in the case: ALWAYS in the case, never in a napkin, pocket, or on the table. This prevents losing them.
- 3. Eat comfortably: Without aligners you can eat anything. There are no food restrictions.
- 4. Brush your teeth: Brush well and floss. Don’t put aligners back with food debris.
- 5. Rinse the aligners: Rinse with cold water before wearing. If possible, clean with neutral soap.
- 6. Put them back on: Make sure they fit completely. Use ‘chewies’ if provided to seat them properly.
How to Clean Your Aligners
Proper cleaning keeps your aligners clear and your mouth healthy
Daily Cleaning (At least twice)
- Rinse with cold water (never hot)
- Apply liquid neutral soap without color or fragrance
- Use a SOFT bristle brush (different from your toothbrush)
- Gently brush inside and outside
- Rinse thoroughly to remove all soap
- Dry with paper or air dry before storing
Deep Cleaning (1-2 times per week)
Use effervescent tablets made for aligners or retainers. Dissolve in water and soak aligners for 15-20 minutes. This removes bacteria, odors, and light stains.
DON’T use these products
- Toothpaste: It’s abrasive, scratches and clouds the plastic
- Mouthwash: Can stain and discolor
- Hot water: Permanently warps the plastic
- Bleach: Damages material and is toxic
- Alcohol: Deteriorates and dries the plastic
- Baking soda: Abrasive, creates micro scratches
Don’t forget the case
Wash your case at least once a week with water and soap. A dirty case contaminates your clean aligners.
Eating with Aligners
Good news: you can eat anything (with one condition)
Always remove aligners before eating or drinking anything other than water
You Can Eat Everything
- Hard foods (apples, carrots)
- Sticky foods (gum, candy)
- Popcorn
- Nuts and dried fruits
- Everything you couldn’t with braces
This is a great advantage over braces!
With Aligners On
You can ONLY drink plain water
NEVER with aligners on:
- Coffee or tea (stains)
- Sodas (acids + sugar)
- Juices (acids + sugar)
- Alcoholic beverages
- Hot drinks (warps)
- Colored beverages
Why is this important?
If you eat or drink with aligners, liquids get trapped between the aligner and your teeth. Sugar and acids cause cavities very quickly because there’s no saliva to neutralize them.
Prevent Staining and Yellowing
Keep your aligners truly invisible
Main causes of staining
- Coffee and tea
- Red wine
- Cola drinks
- Curry and turmeric
- Soy sauce
- Smoking
How to prevent them
- Remove aligners to consume these substances
- Brush your teeth before putting them back
- If you can’t brush, at least rinse your mouth
- Clean aligners immediately if you notice color
- Use effervescent tablets regularly
Already yellow?
If your aligners are already stained, effervescent tablets can help with light stains. For severe stains, you’ll probably need to wait for the next set. Good news is you change aligners every 1-2 weeks.
Changing Aligners
Following your orthodontist’s instructions
How often do you change?
Usually every 1-2 weeks, as indicated by your orthodontist. Follow the exact schedule you were given.
Keep the previous aligner
Always save the previous set in case you lose or damage the current one. You can use it while getting a replacement.
How do I know when to change?
- Follow your orthodontist’s schedule
- Current aligner should feel ‘loose’ (teeth have moved)
- New aligner will feel tight (this is normal)
- Never change early even if it feels loose
When starting a new aligner
- It’s normal to feel pressure for the first 2-3 days
- You can take pain relievers if uncomfortable
- Use ‘chewies’ to seat it properly
- Fit improves after a few days
- If pain is severe or doesn’t fit, contact the clinic
Proper Storage
Avoid loss and damage
ALWAYS in the case
- When eating at restaurants
- At work or school
- During exercise or sports
- Any time they’re not in your mouth
NEVER store in:
- Napkins: They get thrown away by accident (#1 cause of loss)
- Pockets: They warp, break, or get lost
- Unprotected bags: They get dirty and damaged
- On the table: They get contaminated and can fall
ALWAYS carry your case with you. Place it next to your plate when eating to remember to store them.
Common Problems and Solutions
- I lost my aligner (Urgent): Use the PREVIOUS set while contacting the clinic. Never skip to a later one. Schedule an appointment ASAP.
- It broke or cracked (Urgent): If it’s a small crack, you can keep using it carefully. If severely damaged, use the previous one and contact the clinic.
- New aligner doesn’t fit: First make sure you wore the previous one for 22 hours. Use chewies. If it still doesn’t fit after 2 days, contact the clinic.
- Discomfort when wearing: Normal with new aligners (2-3 days). Use pain relievers if needed. If pain is severe or causes sores, contact the clinic.
- Attachment fell off: Not urgent but schedule soon. That tooth’s movement may be affected without the attachment.
- Bad breath with aligners: Improve your cleaning routine. Brush your teeth AND aligners more frequently. Use effervescent tablets.
- Aligners smell bad: Insufficient cleaning. Do a deep clean with effervescent tablets. Make sure to dry them before storing.

Your Check-up Appointments
Less frequent than braces, but equally important
Usually every 6-8 weeks
At each appointment we check:
- That teeth are moving correctly
- That aligners fit properly
- Attachment condition
- Your usage and cleaning technique
- If you need refinement aligners
Even though appointments are less frequent, DON’T postpone them. If treatment isn’t going well, it’s better to catch it early.
Your Journey with Aligners
What to expect during treatment
- Week 1 — Adaptation: Initial pressure, possible speech issues, getting used to removal and insertion routine.
- Month 1-2 — Establishing habits: The 22-hour routine becomes natural. Small movements may already be visible.
- Month 3-6 — Noticeable changes: You’ll start seeing significant differences. Aligner changes become routine.
- Month 6-12+ — Toward the goal: Advanced alignment. Possible refinement phase with additional aligners.
- End of treatment — Your new smile! Attachments removed and you begin retainers to maintain results forever.
Duration varies by case: from 6 months for simple cases to 18-24 months for complex cases.
Frequently Asked Questions
Can I chew gum with aligners?
No. Gum sticks to the plastic and is very hard to remove. Remove aligners if you want to chew gum.
What if I have an important meeting or date?
You can remove them briefly (2 hours max). Store in case and put them back ASAP.
Do they affect my speech?
The first few days there may be a slight lisp. It disappears in a few days as your tongue adapts.
Can I smoke with aligners?
Not recommended. Smoke stains them severely and heat can warp them. Remove them first if you smoke.
Are aligners very visible?
They’re practically invisible at normal distance. Attachments may be slightly noticeable up close, but they’re very discreet.
What if I skip a day?
One occasional day won’t ruin treatment, but teeth can shift back. Resume immediately and don’t make it a habit.
Can I whiten my teeth during treatment?
Ask your orthodontist. Some allow whitening, others prefer to wait until end of treatment.
Does changing aligners hurt?
You’ll feel pressure for 2-3 days with each new aligner. It’s normal and means they’re working. You can take pain relievers if needed.
