A standard manual toothbrush or electric toothbrush brush head should be changed every three months. After three months, the toothbrush bristles become soft and will not effectively remove plaque and food debris. We recommend all patients use a soft bristle brush. Most electric toothbrush heads are only made with soft bristles. For most patients, an electric toothbrush is more beneficial than a manual toothbrush. We most commonly recommend the Sonicare electric toothbrush. In addition, by using the Sonicare electric toothbrush, it is proven to keep your teeth two shades whiter. Ask your hygienist or dentist today which brush would be best for you.
