Last appt was 1.5 hours late. Appt rushed. Went to another dentist for this 6 month appt. Found out Daughter's sealants from last visit at Dr Hills (6 months ago) all need to be replaced. Sealants are supposed to last at least 3 years. Also found out daughter has cavity under the sealant . She never had a cavity before the sealants. New dentist told me I was lucky she only got 1 cavity because the other 3 sealants were in bad condition too.
