Switching Toothbrushes
It may be as simple as switching your toothbrush. Although it’s not commonly discussed, toothbrushes with hard bristles or rubber scrapers may be wearing out your enamel. (Read my story about this here.) If you’re experiencing tooth sensitivity, simply switching to a “super soft” toothbrush without any rubber bristles may make a difference in as quickly as a week.
Keep it Alkaline
Orange juice is a common food that wears enamel extensively and could be contributing to your tooth sensitivity. (Source) Your mouth is in an optimal state for remineralization when it’s alkaline, so avoiding acidic and sugary foods and doing a simple swish of baking soda after every meal may help avoid acid wear and reduce your sensitivity as your teeth remineralize.
Calcium Phosphate
Calcium phosphate has been shown in studies to help teeth remineralize. Make a simple paste of calcium phosphate and water and apply it to your teeth; let it sit 5-10 minutes, swish and spit. Or, if the paste isn’t feasible, swish with a teaspoon of calcium phosphate and 1 cup of water throughout the day. (Find calcium phosphate powder here.)
Ozonated Water
Ozonated water has been shown in studies to reverse early-stage cavities by promoting remineralization, and could help with sensitivity. (Source) (Find a water ozonater here.)
Propolis
Propolis extract has been found in limited studies to both reduce cavity-causing bacteria and to increase hardness of teeth. (Source)(Source) Apply drops to affected teeth 1-2 times a day. (Find propolis extract here.) Avoid propolis if you have allergies to bees, bee products, or pollen.
