Dental Hygiene Keeping your smile healthy and bright requires regular oral hygiene check-ups at Gentle Dental. Root Canal Root canals are a virtually pain-free treatment to remove infected nerves from the root of your tooth, protecting your other teeth and your jaw. Bridges Dental bridges are a great way to replace missing teeth. Your existing teeth are used to literally create a bridge to cross the area where your tooth is missing. Crowns Dental crowns are covers (or “caps”) put on your tooth as a layer of protection and restorative treatment. Dentures Dentures are a replacement for missing teeth that can be removed and put back into your mouth as you please. Bonding Bonding can be used to correct cracks or gaps in teeth, as a filling after a cavity has been removed, or to cover up stains or discolored teeth.
