Craze lines can lead to cavities if they’re deep enough, so if you feel severe bumps when you run your tongue across your teeth, definitely see your dentist.

Note that most dental insurance plans don’t cover bleaching since it’s a cosmetic procedure. A single bleaching session costs $650 on average, but some dentists charge up to $1,000. Keep in mind that bleaching can wear away at your enamel and increase tooth sensitivity. [3] X Trustworthy Source PubMed Central Journal archive from the U. S.

Your insurance probably won’t cover fillings for craze lines and a single filling can cost anywhere from $90 to $250.

Porcelain veneers typically aren’t covered by dental insurance plans and can cost $925 to $2,500 per tooth. Composite-resin veneers are relatively cheaper at $250 to $1,500 per tooth, but they usually don’t last as long as porcelain veneers and are more likely to chip over time.

Custom-fit nightguards are typically more comfortable than generic nightguards sold at drug stores. Grinding your teeth can also cause them to shorten over time. If you find yourself clenching or grinding your teeth during the day, make an effort to cut down on stress via exercise or meditation.

If you want to enjoy coffee, tea, and soda, consider drinking them through a straw but it will not prevent staining completely. Don’t think switching to white wine is a better option because the acidity in white wine breaks down your tooth enamel even more than red wine, inviting stains and erosion. Highly-pigmented berries like blackberries, raspberries, and blueberries can also leave stains.

For instance, if you absentmindedly bite your nails while watching TV or reading a book, squeeze a stress ball or fiddle with a small trinket instead.

Get a reusable metal straw to avoid creating excess waste.

Your teeth are for eating and smiling only! Using your teeth as tools can also cause some of them to loosen over time.

For instance, don’t wash down a bowl of steaming hot curry with a sip of ice water—stick to room temperature water or warm tea.
