Do you need molars?
It’s common for adults to lose a back molar, often to gum disease, tooth decay, or injury. Since back molars don’t affect the overall appearance of your smile, you might be tempted to skip replacing it. That’s not the best idea. Missing a tooth, even just one, can cause severe and permanent damage to your entire mouth.
Which are milk teeth?
Deciduous teeth — also known as baby teeth, primary teeth, or milk teeth — are your first teeth. They start developing during the embryonic stage and start to erupt through the gums about 6 months after birth. All 20 of them are typically in by age 2½.
