You should visit the dentist twice or three times a year. Through examination, the dentist can identify cavities, gum disease (such as gingivitis, periodontitis, fungal infection, cancer lesion, etc.), or any other anomalies (overbite, underbite, overcrowded teeth, anodontia, crooked teeth, etc.) and develop the appropriate treatment.
Teeth can have deep grooves and pits that are very difficult to keep clean. Plaque, which is a nearly invisible film of bacteria and food, collects in these grooves. Every time you eat, the bacteria in plaque forms acid, which can cause the enamel to break down and decay, leading to cavity.
A sealant is a plastic material that is usually applied to the chewing surface of the teeth, which acts as a barrier protecting enamel from plaque and acids. To place sealants, first your dentist thoroughly cleans and dries the teeth, applies a conditioning solution, and then the sealant material is brushed into the grooves of the teeth.
Sealant filling is a very simple procedure, does not cause pain, and only takes a few minutes for each tooth. Sealant lasts a few years before it needs to be replaced. Sealant filling is safe and low cost, but very effective in preventing cavities. This procedure is good for both children and adult.
