A habit of clenching or grinding the teeth (bruxism) is not an obstacle to clear aligner treatment; however, it brings a few points that the doctor needs to take into account in planning and in daily use. Aligners can wear down or crack under clenching force, and attachments (small, tooth-colored bumps bonded to the teeth) can be strained. For this reason, in patients who clench, the extent of the habit is evaluated first, and then the treatment plan is built accordingly. This information is general; the decision for you is made after an examination.
Can someone who clenches their teeth use clear aligners?
In most people, yes. Bruxism alone is not considered an obstacle to clear aligners. What is decisive is the severity of the clenching, the level of wear on the teeth, the condition of the gums and the jaw joint area, and the goal of treatment. At the examination, the doctor looks at the chewing surfaces of the teeth, enamel wear, tenderness in the jaw muscles and the mouth-opening movement. If needed, this is evaluated together with X-rays and photographs.
How intense the habit is affects the choice of aligner and the frequency of follow-up. Mild clenching can often be managed without extra measures. If there is intense grinding, the doctor may want to check the aligners more often, use an additional guard, or, in some patients, manage the habit before starting orthodontic treatment.
For the causes of bruxism and general treatment approaches, you can look at our article on bruxism. If you clench without noticing during the day, the article on daytime teeth clenching will also be helpful.
What does teeth clenching do to clear aligners?
Clear aligners are made of a thin thermoplastic material. Regular and intense clenching force can have the following effects on this material:
- Wear and thinning: On the chewing surfaces, the aligner gradually becomes cloudy and thins; in advanced cases, small holes may be seen.
- Cracks and breaks: Especially with strong grinding, cracking can occur at the aligner edges or in the molar area.
- Strain on attachments: Load builds up on the attachments during clenching; in some patients, attachments may come off or wear down. We explained attachments in detail in our attachment article.
- Fit problems: A worn or cracked aligner may not fit the teeth fully, and the planned tooth movement may slow down.
- Muscle fatigue: Continuing to clench with the aligners in can prolong jaw tiredness in the morning.
Seeing these signs does not mean treatment has failed. The doctor can see the situation and have the aligners remade or rearrange the plan. What matters is that when you notice a crack or a hole, you tell the clinic instead of waiting until your check-up.
Does clenching with aligners in protect the teeth?
This is a frequently asked question. Clear aligners partly cover the chewing surfaces of the teeth and somewhat reduce direct contact between the upper and lower teeth during clenching. However, an orthodontic aligner is not a protective night guard (splint). It is not designed for treating teeth clenching; its thickness, material and bite are not planned like a night guard. For this reason, it would not be right to regard the aligner as a treatment for clenching.
You can find what a night guard is and how it works in our night guard article, and its types in the article on types of teeth clenching guards.
How should clear aligners be used by someone who clenches?
The basic rule does not change: aligners are worn for the period set by the doctor, usually 20–22 hours a day. For people with a clenching habit, a few additional recommendations stand out:
- Wear the aligners at night too. Clenching mostly happens during sleep. Taking the aligners out at night both slows treatment and causes the teeth to grind against each other without the aligners.
- Develop awareness during the day. If your teeth are touching, the lips should be closed, the teeth apart and the tongue resting on the palate. You can set small reminders on your phone.
- Monitor the condition of the aligners. Each time you put in a new aligner, look at the chewing surfaces. If there are shiny wear marks, clouding or a crack, take a photo and send it to the clinic.
- Do not throw away old aligners. If the new aligner breaks, the doctor may ask you to go back to the previous one.
- Avoid very hard foods. Tiring the jaw muscles strains attachments and aligners more.
Is an additional protective guard needed along with the aligners?
This depends on the doctor's evaluation. In some patients, an additional night guard is not recommended during treatment, because the orthodontic aligners are already worn at night. In other patients, when the clenching is severe, when the aligners wear down very quickly, or when marked tiredness in the jaw muscles continues, the doctor may choose a different approach. These can include increasing the aligner change frequency, dividing the plan into stages, or fitting a separate guard for the habit into the treatment sequence. Which one is suitable is decided only after the examination; do not wear a second aligner over the aligner on your own.
There are also muscle-relaxing applications for teeth clenching. Our comparison article comparing botox with the guard method explains these options in a general framework.
What should be reported to the doctor, and when, if you clench your teeth?
| Situation | What to do | When to contact the doctor |
|---|---|---|
| Clouding or mild wear on the aligner | Take a photo and show it at the next check-up | If it increases with each new aligner, let them know without waiting for the check-up |
| Crack or hole in the aligner | Stop using that aligner and go back to the previous one | Call the clinic the same day or within a few days |
| Attachment coming off or wearing down | Keep wearing the aligners, being careful not to swallow the attachment | Make an appointment if the aligner does not seat |
| Jaw tiredness in the morning | Daytime awareness exercises, avoiding hard food | Ask for an evaluation if it has continued for several weeks |
| Jaw joint pain, clicking or limited mouth opening | Report it instead of waiting and forcing | For new or increasing complaints, at the start of or during treatment |
| Increased sensitivity of the teeth to cold | Follow the doctor's recommendation for sensitivity | If it lasts longer than a few days |
What happens if you have a jaw joint complaint?
Teeth clenching can occur together with complaints in the jaw joint (TMJ) area. If there are symptoms such as pain when opening the jaw, clicking or tiredness in front of the ear, this needs to be evaluated before orthodontics. Orthodontic treatment alone does not treat a jaw joint disorder; the doctor considers both the condition of the joint and the treatment plan together. For details, you can look at the page clear aligners and the jaw joint.
What happens if clenching continues after treatment is finished?
When orthodontic treatment is finished, the teeth need a retainer to be held in their new positions. If the clenching habit continues, it should be remembered that the retainer can also wear down. Because clear retainers (such as Vivera) are thin, they can get holes over time with intense clenching. In that case, your doctor may discuss options such as a fixed wire, a retainer of a different thickness, or a separate guard. You can find why the need for a retainer may last a lifetime in our retainer article, and the general process after treatment on the page retainer after clear aligners.
Does teeth clenching change the treatment plan and its duration?
In some patients it can. Clenching force does not directly speed up tooth movement; on the contrary, if the aligner wears down or an attachment comes off, the fit is disrupted and movement can fall behind what was planned. In that case, the doctor may add an interim check-up, ask for an additional aligner set to complete the missing movement (refinement), or follow a different sequence within the plan. The duration varies according to the amount of movement, the aligner wear routine and the person. For the general time framework, you can look at the page how long does clear aligner treatment take. The page clear aligner problems is also useful for solving everyday problems such as aligner breakage, loss and poor fit.
What should you tell the doctor before treatment?
Noting the following points before you go to the examination makes the evaluation easier:
- Whether you experience jaw, neck or temple pain in the mornings
- Whether your partner or family members hear grinding sounds at night
- Whether you have used a night guard before
- Whether your teeth have wear, fractures or sensitivity to cold
- Periods of intense stress and your sleep routine
You can find the general framework for aligner use, wear time and care on the page how to wear clear aligners. The page clear aligner treatment is also useful for the overall flow of treatment.
How are patients who clench their teeth approached at our clinic?
The Invisalign system is used at Funda Sarıkaya Oral and Dental Health Polyclinic. At the first examination, Funda Pekyılmaz Sarıkaya, specialist orthodontist (Uzm. Dt.), evaluates the bite, signs of wear on the teeth and jaw joint findings together. If there is a history of clenching, the plan is shaped accordingly, and the aligner surfaces are examined separately at check-ups. The clinic is located at Park Oran Ofis in Oran, Çankaya, and is open Monday–Saturday, 09:00–20:00. For an appointment, you can use the phone number 0312 911 60 36 or the WhatsApp line.
