How to Repair Teeth Damaged by Grinding in Kids and Teens
Reviewed by Dr. Paul Rubin
Reading time: 5 minutes
Teeth grinding can gradually flatten, chip, or weaken a child’s teeth. The right treatment depends on whether the damage affects baby teeth or permanent teeth, how much structure has been lost, and whether your child has pain or sensitivity.

Can Teeth Worn Down From Grinding Be Repaired?
Dentists can often repair teeth damaged by grinding, but not every worn tooth needs restorative treatment.
The decision depends on:
- Whether the tooth is primary or permanent
- How much enamel or dentin has worn away
- Whether the tooth is painful or sensitive
- Whether it has chipped or cracked
- How long a baby tooth needs to remain in place
- Whether the wear is getting worse
- Whether the child is still grinding regularly
The goal is to protect the tooth while preserving as much healthy structure as possible.
Do Worn Baby Teeth Need Treatment?
Most mildly worn baby teeth do not need to be rebuilt. If the tooth remains comfortable, functions normally, and is not losing structure quickly, we may simply monitor it during routine visits.
Treatment becomes more likely when a baby tooth has:
- Significant loss of tooth structure
- Ongoing sensitivity or pain
- A chip or fracture
- Damage close to the nerve
- Difficulty supporting normal chewing
- Wear that is affecting the bite
- Several years remaining before it should fall out
How long the tooth needs to stay in place also matters. A mildly worn baby tooth that is close to falling out may not need repair. A heavily damaged tooth that must remain functional for several more years may need protection.
How Baby Teeth Are Treated
We will first confirm that the wear is caused by grinding. Tooth decay, acid erosion, reflux, and enamel defects can create similar damage and may require a different approach.
Possible treatments include:
- Monitoring and sensitivity care: Small, smooth areas of wear may be photographed or measured so the dentist can check whether they are changing. Fluoride varnish or a sensitivity toothpaste may help if enamel loss has exposed a more sensitive layer of the tooth.
- Crowns for significant damage: A crown may be recommended when a baby tooth has lost substantial structure but still needs to remain in place. Stainless steel crowns are often used on heavily damaged back baby teeth because they provide durable, full coverage. Tooth-colored options may be considered for visible teeth.
- Pulp treatment: Severe wear may reach or irritate the nerve inside the tooth. Pulp treatment may be needed when the tooth can still be restored and needs to remain in place.
- Removal: Extraction may be recommended if the tooth cannot be repaired, has developed an infection, or is already close to falling out. A space maintainer may be considered when a back baby tooth is removed too early.
The best option depends on which tooth is affected, how much structure remains, whether it is painful, and how long it needs to stay in place.
How Worn Permanent Teeth Are Repaired in Teens
Permanent teeth usually receive more active protection because they need to last throughout adulthood. Treatment typically begins with the most conservative option that can restore comfort, strength, and function.
Repair options may include:
- Composite dental bonding: Tooth-colored composite can rebuild mildly or moderately worn edges, repair small chips, cover exposed dentin, and reduce sensitivity. It preserves more natural tooth structure than a crown but may need maintenance if grinding continues.
- Crowns: A crown may be considered when a permanent tooth has extensive wear, a large fracture, weakened structure, or too little enamel remaining to support bonding. Because a crown requires reshaping the tooth, it is not automatically the first choice for a teenager.
- Staged treatment: In some cases, bonding may protect the tooth while the teen continues to grow. A longer-term restoration can be considered later if necessary.
- Treatment for a damaged nerve: A deep crack or severe wear can irritate or expose the nerve. Additional treatment may be needed if the teen has lingering sensitivity, pain when biting, spontaneous pain, swelling, or a deep fracture.
We will consider the teen’s age, remaining tooth structure, gumline, bite, and long-term restorative needs before recommending treatment.
Can a Night Guard Protect Teeth?
A night guard may help protect permanent teeth, bonding, and crowns from continued grinding. It creates a barrier between the upper and lower teeth and reduces direct contact between the biting surfaces.
A custom night guard may be considered when:
- A teen has noticeable permanent-tooth wear
- Bonding or crowns need protection
- Grinding continues regularly
- The child has jaw discomfort or morning headaches
Night guards are not routinely recommended for every young child. Loose baby teeth, erupting permanent teeth, and growing jaws can make appliance fit more complicated.
A night guard protects the teeth, but it does not necessarily stop grinding. Any contributing sleep, airway, stress, or medical concerns may also need to be addressed.
Signs Worn Teeth Should Be Checked
Schedule a dental evaluation if you notice:
- Teeth becoming shorter or flatter
- Yellow areas showing through worn enamel
- Chipped or cracked edges
- Sensitivity to cold, heat, sweets, or brushing
- Pain while biting or chewing
- Jaw soreness
- Morning headaches
- A filling or bonded area that repeatedly chips
- Grinding with snoring, gasping, or disrupted sleep
Sudden pain, swelling, trauma, or a deeply broken tooth should be evaluated promptly.
Evaluating Worn Teeth at Lonestar Kid’s Dentistry
At Lonestar Kid’s Dentistry, we evaluate how much tooth structure has been lost, whether the wear is progressing, and how your child’s teeth and bite are developing.
Regular dental exams allow us to monitor worn areas over time and identify changes before they lead to pain, sensitivity, or more extensive damage. Some teeth only need continued observation, while others may benefit from treatment to protect their strength and function.

FAQs
Lost enamel does not grow back. Mild wear may only need monitoring, while deeper damage may need to be covered or rebuilt.
Bonding can work well for mild to moderate damage, especially on permanent front teeth. Heavy grinding can eventually wear or chip the material.
Many young children do not need one, especially when the grinding is mild and no damage is occurring. Age, growth, symptoms, and the amount of wear all affect the decision.
Crowns are strong, but repeated grinding can damage the crown, the supporting tooth, or nearby teeth. A custom night guard may help protect the restoration.
It depends on how much damage has occurred, whether the tooth hurts, and how long it needs to remain in place. A mildly worn tooth close to falling out may only need monitoring.
