Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
Dental implants are intended to blend in among your natural teeth.
One of the advantages of this is that you can brush and floss them the same as you would with your regular teeth. While implants never get cavities (and never need root canals!), you still want to continue brushing and flossing to keep your natural teeth and your gums healthy.
