Did you know that tooth enamel is the hardest substance in the entire human body? It’s true, and it’s one reason why dental records are often used for instances involving forensics. Teeth are packed with a dense amount of hydroxyapatite crystals, which makes them even stronger than human bone.
Not every part of a tooth is hard, though. Once you get through the outer shell of enamel — which only covers the crown, or area above the gumlines — you reach the dentin and then the pulp (nerve tissues.) Dentin is much softer. Once a cavity creeps through the strong tooth enamel and reaches dentin, the decay spreads quickly and widely. Why? Because dentin is weaker and less dense.
Compared to adult teeth, baby (primary) teeth are much weaker. They lack the inner dentin structure and are made to resorb when pressed against by adult teeth, which allows them to “shrink” into a shell over time before falling out. As such, they’re usually more prone to fractures of tooth decay.
Although tooth enamel is strong, it’s still susceptible to certain things that can permanently damage your smile. Here are a few examples: Wear (Bruxism): When teeth wear against other teeth abnormally — whether it’s due to a misaligned bite or a clenching and grinding habit like bruxism — your enamel will suffer. Gradually, the teeth will develop jagged or sharp edges, before getting flatter over time. Adjusting how healthy teeth bite together can help to eliminate unwanted wear. Aggressive Toothbrushing: Always use
Dental calculus — commonly referred to as “tartar” — is calcified plaque that’s accumulated across teeth and root surfaces (just under the edges of your gums.) Even if you brush and floss daily, some of the areas in your mouth will tend to develop buildup.Unfortunately, calculus can’t be removed with conventional brushing and flossing. Being that it harbors disease-causing bacteria, tartar buildup will lead to tissue detachment, gum recession, and bone loss.Seeing a hygienist regularly provides an opportunity to have
