Fillings are used to fill holes (cavities) that have formed, usually as a result of decay or tooth wear. There are many types of filling, each suitable for different cavities.
Highly effective in preventing decay on the chewing surfaces of your food grinding teeth, sealants are a simple procedure in which a tooth-colored fluoride releasing material is carefully placed onto the grooves and fissures of the tooth. This effectively “seals” the deep grooves acting both as a barrier and a chemical modifier of the enamel, so when the sealant is worn off the enamel is resistant to plaque and acids.
Quick to apply, sealants hold up well under the force of normal chewing and can last several years before a reapplication is needed.
