Fruits with high levels of Vitamin C and antioxidants can help neutralize the bacteria in your mouth. Apples, strawberries, cranberries, kiwis, and oranges are all good providers of these healthy teeth ingredients.
Swish with water: After eating a piece of fruit, our teeth and mouth will be covered in the acids that the fruit naturally contains. To help ensure that these acids are not slowly damaging our teeth, swish a mouthful or two of water right after you finish eating.
It also helps the cells that are involved in the formation of teeth. Certain fruits such as strawberries, grapefruit, oranges, apples, kiwis, cranberries and limes have high levels of vitamin C and other antioxidants that help maintain the overall health of the oral cavity.
Bananas are full of vitamins like vitamin C and vitamin B6, as well as fiber. In addition, they provide a wide variety of minerals like potassium, manganese, and magnesium. These minerals can help strengthen tooth enamel, so they're very good for the teeth.
While the enamel can't grow back, it can be remineralized with special tooth repair kits. Certain toothpastes and dental products push calcium and phosphates back into the teeth and harden the enamel.
Eat More Enamel-Strengthening Foods
Soybeans in edamame and tofu, broccoli rabe, kale and other leafy greens are leading non-dairy options for adding calcium to your diet. And don't forget to drink plenty of water. Water helps boost your saliva levels, and saliva is how calcium transfers to your teeth.
Vitamin D. Without adequate vitamin D, the healthy power of calcium is severely diminished. Vitamin D acts as a communicator, and signals the intestines to absorb calcium into the bloodstream. Adequate vitamin D and calcium make bones and teeth denser and far stronger, which helps prevent fractures and cracks.
Drinking too much of liquids that are high in acid, like coffee, can weaken your enamel. Your enamel is what protects your teeth, so if it is weakened or wears away, then your teeth become more vulnerable to decay.
Calcium is an important nutrient that people need to consume for strong bones and teeth. When a person does not consume enough calcium, phosphorus, and vitamin D, they can develop weaker, less-dense bones and teeth. This can lead to osteoporosis and other health complications, such as tooth decay and tooth loss.
Once tooth enamel is damaged, it cannot be brought back. However, weakened enamel can be restored to some degree by improving its mineral content. Although toothpastes and mouthwashes can never “rebuild” teeth, they can contribute to this remineralization process.
As the enamel erodes more, your teeth may appear grayish or yellow. Your teeth may begin to appear rounded, develop ridges, and often the gaps between teeth will become more substantial. Eventually, you may notice cracks in the teeth or experience loss of tooth material.
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.
Strengthening Through Diet
If you want to strengthen your teeth through an improved diet, you will need to eat more of certain foods and less of others. Fresh fruits and vegetables are rich in vitamins and minerals, many of which contribute to stronger, healthier teeth.
Eggs. Eggs contain vitamin D, calcium, and phosphorus. Eating eggs in the morning can help teeth form enamel and use minerals. Eating eggs for breakfast can help strengthen teeth and prevent tooth decay.
That's right - according to some experts, eating an apple can actually help remove plaque from your teeth and gums. The reason is that apples contain a type of acid called malic acid, which has been shown to be effective in breaking down plaque and potentially whiten tooth enamel.
Genetics: A genetic predisposition toward softer dentin and tooth enamel can result in discolored, weak teeth that are prone to fracture and damage. Medical Conditions: Some health concerns can lead to weak, brittle teeth, including osteoporosis, eating disorders, and gastroesophageal acid reflux disease (GERD).
