This is not medical advice I am posting this for informational and educational purposes.
To have success in preventing loss of teeth you need to address infections and health issues. I did this to prevent any more loss of teeth and farther bone loss but my bone did not grow back until I had addressed my Lyme disease and the health issues it caused. Something that provides minerals needed is water from a volcanic source or hot spring.
I have watched friends repair cavities by remineralizing them with proper nutritional support and coconut oil flushing. They used straight coconut oil but I have Lyme and it was also causing bone loss so I modified things a bit to help fight the infection and stop the bone loss the Lyme was causing. I got angry because for 5 years dentist would not help me because they said it was not gingivitis so they did not know what to do. When I would go to a doctor they would tell me it was a dental problem and they could not help me. I wish my Facebook friends would have taught me this sooner because I started pulling my teeth and pulled three of them before they posted this. It did save the rest of my teeth though. Because diets do not contain enough healthy animal fats now days to be able to absorb oil soluble vitamins and glyphosate and over farming cause our food to be less nutritious our health and the health of our teeth are declining.
I did not measure I just dumped the stuff in I do that when I cook so I cannot give you the right amounts I would say to do some research. I will estimate the amounts.
In 10 ounces of coconut oil put about 1/8 teaspoon of powdered vitamin C.
Add about a table spoon of cinnamon and a table spoon of curcumin.
Add about a tablespoon of xylitol to the coconut oil.
Mixed it around and let it set for about a week. If you prefer you can use warm water to melt it to make it mix better. Then after letting it set you can repeat the process by setting the container in warm water and then use a filter to filter the coconut oil.
Then take a huge heaping tablespoon full and swish it around in your mouth for at least 15 minutes before bed at night. When finished gargle with it then spit it out but do not rinse go to bed and you will wake up and be pleasantly surprised you will not have the morning gunk that many get even when they brush before bed.
The vitamin C and xylitol helps prevent and fight infection.
As for diet try to avoid processed sugar especially processed can sugar and processed fructose.
Here is are links with great information on nutrient needed for healthy teeth.
Read the comments on this link very interesting.
Lyme may get into the dentin in teeth so this will have to continue for quite a while.
Do not use fluoride or drink fluorinated water. Fluoride makes the teeth brittle.
Brushing your teeth with toothpaste that contains hydroxyapetite also helps remineralize the teeth.
If you smoke stop , smoking has been shown to cause gingivitis.
If you have digestive issues they must be addressed.
Bacteria like lactobacillus, streptoccocus salvarius, streptoccocus mitis, Prevent infection in the mouth nose and through and also help prevent cavities and dental plaque. E Coli Nisle 1977 prevents infection in the mouth and helps prevent halitosis.
Lactobacillus Plantarum prevents biofilm formation in the mouth.
Lactobacillus plantarum prevents oral biofilms, Bifidobacterium and Lactobaccilus Rhamnosus helped prevent cavities. Lactobacillus Salvarius helps prevent dental plaque.
Lactobacillus Reuteri reduces dental plaque, prevents periodontal disease and reduces inflammation. Bifidobacterium Animalis prevents bone loss and gingivitis. Bacillus Subtilis, Bacillus Licheniformis and Lactobaccilus Brevis also prevent bone loss. L Brevis CD2 reduces inflammation and prevents gingivitis. Lactobacillus Rhamnosus, Lactobacillus Casei Shirota, Lactobacillus Reuteri and Bifidobacterium prevents cavities. Streptococcus Dentisani and Streptococcus Salivaries M18 produce bacteriocins which kill harmful microbes they prevent gingivitis and infection.
Lactobacillus Planatarum, Lactobacillus Paracasei, Lactobacillus Salivarius, and Lactobacillus Rhamnosus have antimicrobial properties. Lactobacillus Salivarius and Lactobacillus Gasseri prevent halitosis and prevent opportunistic infections. Weissella Cibaria also prevents halitosis this one also reduces skin lesions.
Streptococcus Thermophilus is a subspecies of Streptococcus Salivarius and has many of the health benefits of Salivarius and also helps with metabolic issues. The commensal Streptococcus strains of microbiota help prevent strept throat.
Though many of these strains can probably be purchased in probiotics I am not going to research that. That is up to the reader.
Streptococcus Salivarius K12 prevents ear infections, inflammation and cavities. This and other beneficial Streptococcus Salivarius strains are used in some yogurts and cheeses so they could be a source of these strains.
Streptococcus Thermophilus is used in low fat cheese so that could be a source of it.
Lactobacillus Plantarum is found in fermented foods and aged meats.
Lactobacillus Paracasei , Lactobacillus Rhamnosus,Lactobacillus Gasseri is found in fermented foods like fermented vegetables or fermented milk products.
Weissella Cibaria is found in Kimchi, and raw milk.
Lactobacillus Reuteri would be found in sour dough but would not survive the cooking process so would have to be purchased in a probiotic.
Bifidobacterium Animalis is found in raw milk and fermented milk products.
Bacillus Subtilis and Bacillus Licheniformis is found in the soil and soil based probiotics.
Lactobaccilus Brevis is found in fermented foods like sauerkraut and fermented pickles.
Lactobacillus Casei Shirota normally has to be purchased and is used to ferment some beverages.
As for the Bifidobacterium I believe the only source I could find was raw milk and probiotics.
Now for bone loss using soup bones and cooking them for 24 hours and consuming the broth will give the nutrient needed for the body to restore lost bone.
Silica is needed for new bone growth.
