At Bright Young Smiles we are constantly implementing new technology to help us make your dental experience comfortable and pain freel. In order to treat your teeth without pain, tooth numbing/local anesthesia, is necessary. Traditionally, local anesthesia is administered with a needle. The numbing done with the needle numbs the entire area around the tooth including the lips and gums. While there may be some procedures requiring traditional injections, the STA is available as an alternative.
