The brand of toothpaste is a personal preference. The important feature you should look for is a fluoride containing toothpaste with the ADA seal of approval. The main purpose of toothpaste is to provide the fluoride your teeth need to help fight cavities.
Toothpastes advertised as whitening toothpaste often have abrasives in them for surface stain removal. Using these excessively can wear away the enamel, leading to sensitivity problems. Tartar control toothpastes often cause staining and are rarely recommended.
Sensitive toothpastes contain an ingredient to help reduce sensitivity to hot and cold. These work well for patients with sensitive teeth but generally need to be used regularly to have an affect.
Some people have a high risk for developing cavities. For these patients, we will prescribe a toothpaste with a different strength of fluoride. This will help to strengthen the teeth and decrease the chance of developing a cavity.
