  • signs of trauma to the teeth or gums like redness, swelling, or bleeding
  • your child appears to have pain or discomfort in their face when they wake up
  • tooth sensitivity when they drink something hot or cold.

Treatments for Teeth Grinding

In the case of older children, dentists often recommend using a nightguard. This is to relieve them of pain or tooth misalignment issues.

Nightguards are thin, flexible pieces of plastic that slip over the upper gums to protect their teeth from damage.

However, the teeth in your toddler are constantly changing which hinders the effects of nightguards to fit well.


However, keep in mind that you should not wake your child up when they grind their teeth at night. This can cause sleep disturbance in your child which can lead to behavioral issues.

Usually, there is no treatment for your toddler’s teeth grinding.

If you think that stress and anxiety may be causing it, you can establish more of a routine with your toddler.

This can include special snuggle time, or reading bedtime stories to help them feel calm and comfortable before drifting off to sleep.

How long does it Last and Prevention

Most of the time, your toddler will stop grinding their teeth when they lose their baby teeth.

However, some kids continue grinding their teeth to adolescence. And if stress is causing bruxism, then it will continue until their stress eases.

As bruxism is your child’s natural reaction to growth and development, most of the time you cannot prevent it.

You can give your toddler a warm bath or shower, play soothing music or read to book to make them comfortable while they drift off to sleep.

But in older kids, if it is due to stress or anxiety, you can talk to your child and help them deal with stress.

For instance, they can be upset about going away from home for their first trip, moving to a new place, or other fears.

Talk to your child and try to help ease their stress. Moreover, taking kids for regular dental checkups can also help find and treat teeth grinding.

The TakeAway

Toddler teeth grinding is often common and does not have any adverse effects on their teeth, as with time, permanent teeth will replace them.

However, if you observe that it is causing sleep disturbances leading to behavioral changes, then you can try giving them a warm bath, or reading a book to make them comfortable before they sleep.

While your toddler has a few more years with their baby teeth, keep in mind that their grinding habits will resolve on their own as they will grow.
