If you grind or clench your teeth at night, you might be wondering whether clear aligners are still an option for straightening your smile.
The good news is that most people who grind their teeth can still be suitable candidates for clear aligner treatment. In fact, because aligners are worn 20-22 hours a day, they also provide a protective barrier between your upper and lower teeth throughout treatment.
It’s important to remember, however, that clear aligners are designed to straighten teeth, not treat teeth grinding (bruxism). Any protection they provide is simply an added benefit of wearing them, rather than their intended purpose.
Here’s what you need to know.
What Is Teeth Grinding (Bruxism)?
Bruxism is the involuntary habit of clenching or grinding your teeth. It often happens during sleep, although some people also clench their teeth during the day without realising it.
Over time, grinding can place significant pressure on your teeth and jaw.
Common signs of bruxism include:
- Waking with jaw pain or tightness
- Morning headaches
- Worn or flattened teeth
- Chipped teeth or cracked fillings
- Tooth sensitivity
- Clicking or soreness around the jaw
Bruxism can have many contributing factors, including stress, sleep disorders and certain medications. If you think you grind your teeth, it’s worth mentioning it to both your dentist and orthodontist.
Is Clear Aligner Treatment Suitable if You Grind Your Teeth?
Yes, in many cases.
Grinding your teeth doesn’t automatically rule you out for clear aligner treatment. During your consultation, your Specialist Orthodontist will assess your teeth, bite and overall oral health to determine whether clear aligners are the right option for your individual needs.
If you already know you grind or clench your teeth, let us know during your consultation. It’s an important part of understanding your oral health and planning your treatment.

Why Clear Aligners Can Be a Good Option if You Grind Your Teeth
If you’re already planning to straighten your smile, clear aligners offer an additional advantage for people who grind or clench at night.
Unlike braces, aligners completely cover your teeth while you’re wearing them. Because you’ll wear them for 20–22 hours a day, including while you sleep, they create a thin barrier between your upper and lower teeth.
This helps reduce direct tooth-on-tooth contact while you’re wearing your aligners, which may help minimise further wear to the surfaces of your teeth during orthodontic treatment.
This protective effect is simply a result of how aligners are designed. Their purpose remains to gently move your teeth into their planned positions, not to manage or treat bruxism.
Will Grinding Damage My Aligners?
People who grind heavily may notice their aligners show signs of wear sooner than someone who doesn’t.
You might notice:
- Surface scratches
- Cloudiness
- Wear on the biting surfaces
- Occasionally, small cracks or splits
Because aligners are replaced regularly throughout treatment, some wear is completely normal.
However, if an aligner becomes cracked, no longer fits properly or is significantly damaged, contact the Urban Smile team via the Dental Monitoring app. We’ll advise whether you should continue wearing it or move to your next aligner.
Do Clear Aligners Treat Teeth Grinding?
No. Clear aligners don’t stop you from grinding your teeth or treat the underlying causes of bruxism.
Their job is to straighten your teeth. The protective barrier they provide while you’re wearing them is simply an additional benefit for patients who grind during sleep.
If your grinding is severe, causing ongoing pain or resulting in significant tooth wear, your dentist or another healthcare provider may recommend further assessment or additional management.
When Should You Mention Teeth Grinding?
Be sure to mention it during your consultation if you:
- Wake with jaw pain or headaches
- Have been told you grind your teeth while sleeping
- Have noticed worn or chipped teeth
- Frequently clench your jaw
- Have broken dental restorations due to grinding
Providing a complete picture of your oral health helps your Specialist Orthodontist recommend the treatment that’s right for you.
Frequently Asked Questions
Can I get clear aligners if I grind my teeth?
Yes. Most people who grind their teeth are still suitable candidates for clear aligner treatment. Your Specialist Orthodontist will assess your individual needs during your consultation.
Are clear aligners better than braces if I grind my teeth?
Every smile is different, but one advantage of clear aligners is that they cover your teeth while you wear them, including overnight. This provides a protective barrier between your upper and lower teeth during treatment.
Can clear aligners replace a night guard?
No. Clear aligners are orthodontic appliances designed to straighten teeth. They should not be considered a replacement for a custom night guard or other treatment recommended for bruxism.
Will grinding ruin my aligners?
Most patients who grind their teeth complete treatment successfully. Heavy grinding may cause aligners to wear more quickly, but because they’re replaced regularly, this usually isn’t a problem. If an aligner cracks or no longer fits properly, contact Urban Smile via the Dental Monitoring app.
