Fluoride

Fluoride treatments are a simple, effective way to strengthen tooth enamel and reduce the risk of cavities. At Crosstown Hershey Dental, professional fluoride is often recommended for children, teens, and adults who are more prone to tooth decay, sensitivity, or enamel wear. Fluoride works by helping enamel rebuild (remineralize) after exposure to acids from bacteria, foods, and drinks—and it can also make teeth more resistant to future acid attacks.

During a routine visit, a fluoride treatment is quick and comfortable. After your cleaning, your dental team applies a concentrated fluoride varnish, gel, or foam to the teeth. The application takes only a few minutes, and the fluoride continues working as it absorbs into the enamel. You may be advised to avoid eating, drinking, or brushing for a short period afterward, depending on the type of fluoride used.

Fluoride is especially beneficial for patients who have frequent cavities, dry mouth, gum recession with exposed root surfaces, orthodontic appliances, or a history of deep fillings and crowns. It can also help reduce tooth sensitivity by strengthening weakened areas and protecting exposed dentin.

For children, fluoride supports developing teeth and helps prevent decay in hard-to-brush areas. For adults, it can be an important part of preventing new cavities and slowing early enamel breakdown—particularly if diet, medications, or medical conditions increase your cavity risk.

Your dentist at Crosstown Hershey Dental will recommend a fluoride schedule based on your individual needs. Combined with regular cleanings, good brushing and flossing habits, and a balanced diet, fluoride treatments are an easy step that can make a big difference in keeping your smile healthy, comfortable, and strong.
