Dental clinic in 200 feet radial road. How does a dentist repair a chipped or broken tooth? Seeing a dentist as soon as possible for a chipped or broken tooth could make a big difference. Your dentist can take x-rays to determine how extensive the damage is and develop the best treatment plan. If you have a cracked tooth, it may be possible to repair the tooth with bonding or dental filling. Your dental team would use an adhesive material followed by a bonding material that can be adjusted to resemble your tooth. The bonding material hardens under a special ultraviolet light. More severe injuries to the tooth could require a dental crown for support. Your dentist would file down the remaining tooth and attach a crown to protect your nerve and look like your original tooth. In extreme cases where the root sustains damage, your dentist may need to extract the tooth. They can then replace the missing tooth with a bridge or dental implant to restore your smile.
