Cavities are fact of life. Even though we brush and floss as we should, cavities still happen. Age and soft teeth certainly don't help. Dental fillings are quick and painless. Decay is removed from the cavity, the tooth is prepared and filling is completed with a composite resin the color of your teeth. Regular dental care and proper home dental hygiene is our best defense against tooth decay. If cavities are too large or a tooth's strength is a concern, or a number of other factors are present, the need for a dental crown rather than a filling might be the better option.
