White Spot Lesions

If you had an early-stage dental infection, would you be able to recognize it? We’re committed to preventive care at Healthy Smiles Family Dental in Salem. As part of our effort, we want each of our patients to understand what a white spot lesion signifies and what they need to do if they develop one.


As the first sign of tooth decay, white spot lesions are also known as “incipient lesions.” They are spots on the surfaces of teeth that appear unnaturally white and chalky and are usually found near the gum line or the sides of teeth. White spots are caused by enamel having lost minerals, but not enough to form a cavity. The teeth naturally produce a film which sugar and the bacteria that feed on it get trapped in. As bacteria eat, they excrete acid, which erodes the enamel. The more food is available, the more bacteria multiply, and the more acid is produced.


It only takes about a month for white spots to develop. Patients should take them as a sign they need to improve their brushing, particularly if they see white spots developing around orthodontic brackets. Infections can be halted before any permanent damage is done, but at the patient’s next cleaning, we’ll need to inspect the lesions to see if they’re still active. Although teeth cannot rebuild matter lost to a cavity, they can recover their minerals. If a white spot has become a permanent scar, we may be able to cover it with a veneer or bonding.

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. At Healthy Smiles Family Dental, Dr. Na Xu gives patients the option to whiten in-office, or in the comfort of his or her own home. Teeth bleaching is one of the most common dental procedures that is performed across the country.

If you have questions or concerns regarding teeth whitening or bleaching, please give us a call. To learn about services provid...

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...
