Dental health


Eating well is essential for living well and aging well. It is no coincidence that in recent years advertising campaigns have intensified to extol the effects of good nutrition.  The upkeep  of your dental capital also goes through a reasoned diet.  

Foods to be preferred  ​

Natural products, without transformation of course!  Pre-prepared and processed products, often saturated with sugar and salt, should be avoided as much as possible. Vegetables provide minerals, vitamins, fiber and many antioxidants that are beneficial for your health.  


Here are some examples :  

  • Vegetables chewable promote chewing, salivation and therefore the elimination of dental plaque and acids harmful to the enamel (radish, zucchini or raw carrots),

  • Green vegetables are often rich in calcium and fluoride and do not contain sugar or acid (green beans, leeks, etc.),

  • Pulses are rich in carbohydrates and proteins. Their nutritional value is important, they are particularly popular with vegetarians and athletes (lentils, chickpeas, soya, etc.),

  • Cruciferous vegetables have been studies demonstrating their preventive effects against cancer. They are rich in vitamin C and calcium which promotes good enamel mineralization (cauliflower, kohlrabi, broccoli, etc.),

  • Still water is the drink that should accompany your meals. To be completely exact, all waters are not created equal, it is necessary to favor waters with a pH> 7 and loaded with minerals (SPA, Évian are quality references). AT  on the other hand, sparkling water is less favorable for your enamel because they are often acidic. Brands are preferred, such as Vichy or St-Yorre, but are also too rich in sodium.  To qualify, however, compared to much more harmful sodas.

  • AD of animal origin are particularly important for vitamin B12 in the process of healing and nerve regeneration.

  • Fish provide essential fatty acids in our body and are also an important source of vitamin D. Vitamin D deficiency can lead to periodontal disease .  

  • The oilseed crops for their seeds. In addition to their nutritional qualities (rich in fiber and nutrients) they promote chewing and therefore the production of saliva (almonds, walnuts, hazelnuts ...)

Foods to Avoid

  • Citrus fruits (oranges, lemons, grapefruit ...) are highly acidic and therefore harmful to the enamel. Even if they are rich in vitamin C, they should be consumed in moderation,

  • Sodas, in addition to their acidity,  are high in sugar. They are a major scourge for oral health. Be careful, diet or Zero sodas are just as harmful.  

  • Alcohol will cause dehydration and therefore dry mouth. Saliva is no longer present in sufficient quantity to ensure its protective role.  

  • Candy and sweets of all kinds, are saturated with sugar.  

  • White bread has a high glycemic index, it is low in fiber and nutrients. Its nutritional value is therefore low. Prefer wholemeal bread which has a good supply of slow sugars thanks to the fibers it contains.

Food to consume in moderation

Junk-food, in great moderation!
