What are Sealants?


toothpaste_free.jpgTooth decay is a common problem, especially among children and older people. Regular brushing and flossing is essential to preventing it, but their are supplementary measures people can take, too. At Healthy Smiles Family Dental in Salem, we offer our patients dental sealants for added protection.


Our back teeth, the premolars and molars, are especially vulnerable to decay. Food debris can accumulate in the indentations between their pointy bits, which are called cusps. There, oral bacteria will feed and produce acid, causing demineralization of the enamel. This could lead to the formation of cavities, and if the decay gets bad enough, an infection could spread to the dental pulp.


Sealants are invisible plastic shields on the teeth. After a dental cleaning, the patient is given a local anesthetic and the premolars and molars are etched with a mild acid to increase their surface area. The sealant is then painted on in liquid form and hardened with a blue light. By the next day, the patient should be eating normally. The sealant not only protects the teeth from acid, but also slightly smooths out the crevices while preserving the teeth’s chewing function. With regular oral hygiene, a sealant can last for years.

Benefits of Teeth Whitening

Teeth become discolored by the foods we eat, the beverages we consume, and from lifestyle factors such as smoking, or taking certain medications. Discoloration is a natural part of life but when a patient desires a whiter smile, teeth whitening or bleaching can improve the color of teeth by several shades.

Teeth bleaching is one of the most common dental procedures that is performed across the country.

Gum Disease Stage 2: Periodontitis

When gingivitis is left untreated, it will advance to periodontitis. Periodontitis is inflammation of the gums and supporting structures of the teeth. When periodontitis is left untreated, teeth can eventually fall out. Our doctors at Healthy Smiles Family Dental want patients to keep their permanent teeth for a lifetime, which is why we encourage all of them to take preventive measures when it comes to oral health. Periodontitis is caused by the build-up of bacteria in the form of dental plaque. The best way to avoid plaque build-up is by keeping the teeth as clean as possible by brushing at least twice a day for two minutes and flossing at least once a day. As inflammation progresses in the gums, it will cause the gums to recede and the tooth roots to become exposed. This will cause pain, sensitivity, and soreness. Healthy gums are firm and pink in color, if your gums don’t fall into this category, schedule an appointment, today. If you have questions or concerns regarding periodonta...
