Here are some hilpful tips and tricks to avoid and prevent any damage that is done by me. (I don't WANT to show you this but I feel like I have to, so you're welcome. I guess.)
Brush with fluoride toothpaste after eating or drinking.
You should be brushing your teeth AT LEAST two times a day and more ideally would be after every meal, using toothpaste that does contain fluoride. To clean between your teeth, floss or use an interdental cleaner. If you don't have time to brush after every meal, you can rinse your mouth with just water to get rid of any excess bacteria.
Rinse your mouth.
Sometimes a dentist might feel like you have a high risk of developing cavities, they may recommend you to start using a mouth rinse with fluoride in it to help prevent them from forming.
Visit your dentist regularly.
Get you teeth cleaned professionally and have regular oral exams, which can help greatly when trying to prevent problems or can spot them early on and take action to get rid of them.
Consider dental sealants.
A sealant is a protective plastic coating that will be applied to the chewing surface of the back of your teeth. This will seal off the grooves and crannies that tend to collect food the most. The sealant will protect your tooth enamel from plaque build up and acid.
Drink some tap water.
Almost all public water supplies have added fluoride in them, which has helped significantly decrease tooth decay and cavities. If you're only ever consuming bottled water that doesn't contain fluoride, you'll miss out on the several benefits that fluoride contains.
Avoid frequent snacking and sipping.
If you eat or drink beverages other than water, you're unfortunately helping your mouth bacteria create acids that can destroy your enamel on your teeth. If you snack or drink throughout the day use the tips above to help you out. And because it's basically impossible to just stop eating and drinking throughout the day, try drinking with a straw to prevent the sugars from the drinks touching your teeth.
Eat tooth-healthy foods.
There are certain foods and drinks which are better for you and your teeth than other. Try to avoid the foods that get stuck in grooves and pits of your teeth for long periods of time, such as chips, candy or cookies, or you can brush them soon after consumption of them. With foods such as fresh fruits and vegetables can increase the flow of saliva in your mouth, and unsweetened coffee, tea and sugar-free gum help wash away food particles.
Consider fluoride treatments.
Your dentist may recommend to you that you should get periodic fluoride treatments if they think its necessary for your health especially if you aren't getting enough fluoride through fluoridated drinking water and other resources.
Ask about antibacterial treatments.
If you appear to be especially vulnerable to tooth decay — for example, because of a certain medical condition you may have — your dentist could possibily recommend a special antibacterial mouth rinse or some other treatments to help cut down on harmful bacteria in your mouth that are causing damage to your teeth
