 As always, as soon as I returned to New England, I made a visit to Perfect Smiles. Dr. Helden and his team are the best in New England and I think the whole country. When you're planning dental work, you want to be confident about the quality of the staff and their work. Perfect Smiles has an easy-to-get-to office in Nashua, New Hampshire, right over the Massachusetts border. And it's a comfortable office, too. Before my dental appointment, I sat in their massage chair in the lobby for about a half an hour.
