Is it necessary to get dental cleanings every 6 months?

NO: But a good practice in general to keep your teeth for life. Some need more care, some need less. Talk with hygienist and dentist and make a plan specific to your periodontal and chronic plaque siituation, .

Yes: Surely recommended..To detect any cavities or gum disease at early stage before it worsens.

Cleanings 6 months: Yes cleaning very six months are great for your gum tissues, but also allow a professional to take a peek at them and the teeth so anything posing a potential problem may be averted. Most folks have 28teeth/ 5 surfaces per tooth/ crownsb/fillings etc that do break over time. It is better to catch a problem early than to wait a year to discover this.
