Most people understand the importance of having oil changes at the frequency their car manufacturers recommend but sometimes this same logic isn't as convincing where their teeth are concerned. It should be pointed out that taking care of ones teeth is probably more important than car maintenance. A car can be replaced with a newer and better model, but really teeth really can not. Fortunately missing teeth can be replaced with dentures, fixed bridges and implants, but these approximations are not truly as versatile as ones own teeth .
Teeth that are well cared for both at home and by the dentist can last a lifetime! Why not "get with the program" and have twice a year cleanings?
