You should know that rare problems can happen. These include breathing issues or root resorption. Serious cases do not happen often. Always listen to your dentist for the safest results.
Clear aligners are safe for most people. They feel comfortable when a dentist helps you use them.
You should wear aligners 20 to 22 hours each day. Listen to your dentist’s advice for the best results.
Brush and floss your teeth to keep your mouth healthy. Visit your dentist often to stop side effects during treatment.
Some people should not use aligners. This includes people with serious dental issues or some health problems. Always ask your dentist first.
You use clear aligners to straighten your teeth with a series of custom-made trays. Each tray fits snugly over your teeth and moves them a little at a time. Dental aligners rely on two main systems. The first system shapes the removable trays to match the next step in your treatment. Your teeth shift until they fit the new tray. The second system uses special pressure points and attachments. These help aligners move teeth by tipping, rotating, or even controlling roots. You change your aligners every one to two weeks. This keeps your treatment moving forward.
Clear aligners work best for mild to moderate cases. You must wear your aligners 20 to 22 hours each day. If you do not follow this rule, your teeth may not move as planned. SmileyNova and other dental aligners do not use wires or brackets. This means you feel less pain and enjoy better comfort. You also find it easier to keep your teeth clean. Clear aligners preserve the angle of your teeth well, especially if you do not need extractions. However, they may not work as well for complex movements like root control or fixing severe crowding.
Tip: Always follow your orthodontic treatment plan and wear your aligners as directed. This helps you get the best results.
You may wonder how clear aligners compare to fixed braces. The main difference is that aligners are removable. You take them out to eat, brush, and floss. Fixed braces stay on your teeth until your treatment ends. SmileyNova and other clear aligners offer more comfort and better oral hygiene. You will notice less pain and fewer problems with eating or smiling.
Here is a quick comparison:
Aspect | Clear Aligners (Removable) | Fixed Braces |
|---|---|---|
Oral Hygiene | Easier to clean teeth | Harder to clean teeth |
Comfort | Less pain, more comfort | More pain, less comfort |
Treatment Duration | Often shorter | Sometimes longer |
Tooth Movement Control | Good for simple cases | Better for complex cases |
Psychological Well-being | Higher | Lower |
You get better gum health and less inflammation with clear aligners. SmileyNova and other aligners may not control tooth rotation or root movement as well as braces. Fixed braces use wires to move teeth in more complex ways. You need more appointments with braces. Clear aligners give you more freedom, but you must remember to wear them as directed.
When you start using clear aligners, you may notice some side effects. Most people feel mild discomfort as their teeth move. This pain usually goes away after a few days. Some people notice a small lisp or changes in how they talk. It can cause a lisp at first, but it often gets better as you practice speaking. If you still have trouble after a few weeks, your aligners might not fit right. You should talk to your dentist if this happens.
Your gums or soft tissues might get irritated. You could feel sore spots on your cheeks, lips, or tongue. These spots usually heal as your mouth gets used to the aligners. Orthodontic wax can help with irritation. Most people do not have lasting speech or gum problems. A study found that 93% of users had no speech problems after a few months.
Some side effects are less common but can be more serious. The table below shows the most reported side effects from a ten-year review of use:
Side Effect | Number of Reports |
|---|---|
Difficulty breathing | 56 |
Sore throat | 35 |
Swollen throat | 34 |
Swollen tongue | 31 |
Hives and itchiness | 31 |
Anaphylaxis | 30 |
Swollen lips | 27 |
Feeling of throat closing/airway obstruction | 24 |
Chest pain | 19 |
Cough | 19 |
Nausea | 18 |
Difficulty swallowing | 12 |
Dry mouth | 11 |
Headaches | 10 |
Swelling of eyes | 9 |
Blisters or sores on lips | 9 |
Fatigue | 8 |
Burning/tingling/sore tongue | 7 |
Blisters or ulcerations on tongue | 6 |
Swelling of gums | 5 |
Note: Most side effects are mild and go away soon.
Clear aligners use special medical-grade plastic. Manufacturers pick these plastics because they are safe and work well. Research shows clear aligners made from these plastics do not release harmful chemicals during normal use. Some studies found tiny amounts of BPA or other chemicals can come out if you put aligners in hot drinks or eat acidic foods. These levels are very low and not dangerous. You should avoid hot drinks and acidic foods while wearing aligners to lower any risk.
Tip: Clean your aligners every day and keep them in their case when you are not wearing them. This helps stop bacteria from growing and keeps your aligners safe.
Having a dentist watch your treatment makes clear aligners much safer. Dentists can spot early signs of trouble, like gum swelling, pain, or aligners that do not fit well. They can change your plan to keep your teeth healthy. Treatments without a dentist, like mail-order aligners, can miss hidden dental problems. This can cause gum disease, tooth loss, or bite issues.
Clinical research supports the safety of clear aligners:
Clinical trials show clear aligners help keep gums healthy and lower the risk of gum disease.
Studies find bone problems are less common or about the same as with braces.
Reviews say root resorption is rare and can be managed with regular check-ups.
Over 5,000 research papers, including clinical trials and reviews, support the safety of clear aligners.
New designs and digital planning make treatment safer and more accurate.
Remember: Dentist-guided treatment gives you the best chance for safe, effective results. Always follow your dentist’s advice and tell them about any strange symptoms right away.
You want your teeth to look straight and healthy. Clear aligners help you do this in a comfortable way. SmileyNova and other aligners use trays made just for you. These trays move your teeth a little at a time. You wear each tray for one or two weeks. This works best if your teeth are only a little crowded or have small gaps. If your teeth are just a bit crooked, clear aligners can fix them well.
Studies show clear aligners work 80% to 90% of the time for mild or moderate cases. Most can fix crowding in the upper teeth about 87% of the time. For lower teeth, it works about 81% of the time. You get the best results if you wear your aligners 20 to 22 hours every day. If you listen to your dentist, you will see good results and your aligners will not be easy to see.
Clear aligners work well for these problems:
Mild crowding
Small spaces between teeth
Minor tooth turns
Teeth moving after old braces
Some cases where premolars are taken out
You may see your teeth get straight faster with aligners than with braces. Studies say clear aligners take about 18 months to work. Braces usually take about 24 months. You will feel less pain and be happier with aligners. SmileyNova and other aligners make it easier to keep your teeth clean. This helps your gums stay healthy.
Tip: If you want a comfy and almost invisible way to straighten your teeth, clear aligners are a great choice for mild or moderate problems.
You might ask if clear aligners are right for you. Most people pick aligners because they are comfy and hard to see. They help straighten teeth in a simple way. You are a good fit if your teeth are a little crowded or have small gaps. Aligners work best for adults and teens who follow directions well.
Here are the main things that make someone a good candidate:
Teeth are a little crooked or crowded
Small spaces between teeth
Healthy gums and no tooth decay
You wear aligners 20-22 hours each day
You have most or all adult teeth
You keep your teeth clean every day
You go to the dentist for check-ups
Look at the table below to see how age groups match with aligner use:
Age Group | Recommendation Summary | Dental Conditions Suitable for Clear Aligners |
|---|---|---|
Children (6-10) | Special choices for early jaw or spacing problems | Jaw alignment, spacing before adult teeth |
Adolescents | Good for mild or moderate tooth problems | Mild crowding, stops bigger problems |
Young Adults | Popular for hidden teeth straightening | Mild crowding or crooked teeth |
Adults | Good for missed or relapsed treatment | Mild orthodontic problems |
Seniors | Possible if teeth and gums are healthy | Mild alignment, keeps mouth healthy |
Note: You need a dentist to check your teeth before you start. Your dentist will see if aligners can move your teeth safely.
Clear aligners are not right for everyone. Some health or dental problems make aligners less safe or less helpful. If your teeth are very crowded or have big gaps, you may need braces.
See the table below for who should avoid aligners and why:
Patient Populations / Medical Conditions | Reason for Avoidance / Contraindication |
|---|---|
Certain medicines (like NSAIDs, bisphosphonates) | More risk of problems |
Bleeding disorders, sickle cell anemia, diabetes | Higher risk of problems |
Epilepsy, chemotherapy, radiation therapy | Possible problems |
Dry mouth, smoking, allergies | More trouble with aligners |
Gum disease history | Risk of gum damage |
Dental Conditions | Reason for Avoidance / Contraindication |
|---|---|
Big gaps or crowding (over 5 mm) | Hard to fix with aligners |
Jaw or bite problems | Not safe for aligners |
Severe tooth rotation or extrusion | Hard to fix with aligners |
Many missing teeth | Not safe for aligners |
Bad oral hygiene | Risk of problems |
If you have cavities, gum disease, or do not clean your teeth well, you should not use aligners yet. Aligners can trap food and germs, which may cause stains, cavities, or gum problems. You must brush and floss after eating and clean your aligners every day to stay safe.
Tip: If your gums hurt or bleed, call your dentist soon. Keeping your teeth clean and seeing your dentist helps you get the best results.
You play a big role in the success of your clear aligner treatment. Dental professionals recommend these steps for safe and effective results:
Wear your aligners 20-22 hours each day. Remove them only for meals and oral care.
Change to new aligners every 10-14 days, or as your dentist tells you.
Use aligner seating tools or chewies for 10-15 minutes daily to help your aligners fit well.
Never eat or drink anything but water while wearing aligners. This keeps your aligners clean and prevents damage.
Store your aligners in their case when not in use. Avoid wrapping them in napkins or leaving them out.
Attend all dental check-ups so your dentist can track your progress and make adjustments.
Contact your dentist right away if you lose or break an aligner.
High compliance with these steps helps your teeth move safely and keeps your treatment on track. Skipping steps or wearing aligners less often can slow your progress and affect your results.
Good oral hygiene is key when you use clear aligners. Aligners cover your teeth, so food and bacteria can get trapped if you do not clean well. Follow these tips to keep your mouth healthy:
Brush your teeth with a soft toothbrush and fluoride toothpaste every morning and night.
Floss once a day to remove food between your teeth.
Brush and floss after every meal before putting your aligners back in.
Rinse your aligners with lukewarm water each time you remove them.
Clean your aligners gently with mild soap and a soft brush. Do not use toothpaste or hot water.
Soak your aligners in a cleaning solution or use an ultrasonic cleaner for deep cleaning.
Store aligners in a clean case to avoid germs.
Poor oral hygiene can lead to plaque, cavities, and gum disease. Studies show that bacteria can build up on aligners and teeth, raising your risk of dental problems. Cleaning both your teeth and aligners every day helps prevent these issues.
Tip: Carry a travel toothbrush and floss so you can care for your teeth and aligners when you are not at home.
Sometimes, you may notice problems during your treatment. Contact your dentist right away if you have any of these signs:
Severe or ongoing pain in your teeth or jaw
Lost, broken, or ill-fitting aligners
Bleeding or swollen gums that do not get better
Sores or cuts from your aligners
Bad taste or breath that will not go away
Difficulty chewing or biting food
No progress in your teeth alignment after several weeks
Complication | What to Watch For |
|---|---|
Improper fit | Aligners feel loose or do not fit teeth |
Gum or soft tissue injury | Cuts, swelling, or pain in your mouth |
Severe pain | Pain that does not improve with time |
Lost or broken aligners | Missing or damaged trays |
Quick action helps prevent bigger problems and keeps your treatment safe and effective.

If you lose an aligner, contact your dentist right away. Your dentist will tell you if you should use your last set or move to the next one. Quick action helps keep your treatment on track.
You may feel mild discomfort when you start a new set of aligners. This feeling means your teeth are moving. The pain usually goes away after a few days. If pain lasts, talk to your dentist.
You can use clear aligners if you have crowns. Aligners may not move dental implants because implants do not shift like natural teeth. Your dentist will check your mouth and decide if aligners work for you.
