Dr. Koppe got me in on a Saturday for an emergency tooth repair when I broke a molar, put on a temporary crown which held for months while I built up the courage to go back and get my crown. I'm terrible about having someone working in my mouth, but Dr. Koppe was extremely professional, gentle, and efficient. His office is comfortable without any flash, but his staff are first rate! Even my cleaning was pain-free and pleasant. I recommend the gas if you're queazy about dental work, it made all the difference for me!!!
