1 /5 Luckylillylou Koehler: Do not understand where all of the positive reviews came from. Was patient for 2 years - first 2 cleanings everything was great. Last cleaning I needed a root canal, which he covered with a filing. Have since found out that is a no no. Now in addition to needing a crown where he put a filing and also need 3 more crowns and need to see an oral surgeon. Have been told by new doctor that there is no way these issues just came up after my last cleaning in June. Very upset.
