Does vitamin C help maintain good oral health?

Oral health: an often neglected pillar

Much more than a simple point of entry for food, the mouth reflects the general state of the body.

When the oral balance is compromised, warning signs can appear: sensitive or irritated gums, bleeding when brushing, sensitivity to heat or cold...

If left untreated, these disorders can develop and compromise the health of the gums and teeth (leading to cavities or periodontal problems).

Poor oral health can also have an impact on overall health, by encouraging the onset or worsening of certain diseases (cardiovascular disease, diabetes, COPD, etc.) (1-3).

So taking care of your gums and teeth is not an option, but a genuine long-term health insurance policy.

And some studies suggest that vitamin C could play a role in oral health and balance.

The role of vitamin C in oral health

While it is no substitute for regular brushing and dental check-ups, a number of recent studies suggest that vitamin C could help to preserve oral health and maintain a healthy smile for the long term.

Vitamin C: essential for collagen formation

Vitamin C contributes to the normal formation of collagen, a protein required for the normal functioning of blood vessels, bones, cartilage, skin, teeth and gums.

Collagen plays an important role in maintaining the strength and elasticity of the tissues that support the teeth (4).

Without this support, the gums can become more fragile and less able to cope with daily stresses.

Support for periodontal problems

A recent study (5) indicates that a higher intake of vitamin C is associated with a reduced risk of periodontal disorders.

These disorders affect the tissues that support the teeth (gums, ligaments, alveolar bone). They often result in chronic inflammation, bleeding or progressive loosening of the teeth.

Their development can be amplified by oxidative stress, which weakens the ability of gum tissue to regenerate and encourages its destruction (6).

A powerful antioxidant (7), vitamin C could help neutralise free radicals and limit gum inflammation, indirectly preserving the integrity of the gums.

Another study had already shown that a sufficient intake of vitamin C seemed to promote better periodontal health, by reducing the frequency of gingival bleeding in gingivitis (8).

Healing and natural defence

By contributing to the normal formation of collagen, vitamin C is also thought to have a positive impact on the healing process (9).

An optimal intake of vitamin C could therefore help accelerate tissue repair in the event of micro-injuries in the mouth (ulcers, irritations, etc.).

Where can I find vitamin C? Food and food supplements

Vitamin C must be taken in every day through food, as our bodies do not synthesise it. And when the diet is not rich or diversified enough, targeted supplements can also help meet daily vitamin C requirements.

Foods rich in vitamin C

To ensure an optimum daily intake, opt for foods that are naturally rich in vitamin C:

• citrus fruit (oranges, grapefruit, lemons, etc.): traditionally known for boosting immunity and supporting vitality
• red fruit (blackcurrants, strawberries, blueberries, etc.): rich in antioxidants, they also provide a significant dose of vitamin C
• kiwi fruit: a good source of vitamin C, perfect for breakfast
• red and green peppers: one of the vegetables richest in vitamin C
• cabbage (broccoli, kale, Brussels sprouts, etc.): excellent for overall health, easy to add to hot dishes
• fresh parsley: sprinkle over your dishes for extra vitamin C

In principle, a varied diet can cover daily vitamin C requirements (100 mg/day for an adult) (10).

But be careful! Certain factors (such as stress, smoking or ageing) can considerably increase your needs. To find out more, always ask your doctor for advice.

Food supplements: various forms for every need

When diet is not enough, or for targeted support, vitamin C supplements can be a viable option.

You can opt for vitamin C in liposomal form. Encapsulated in a microscopic fatty layer (which protects vitamin C from stomach acid), it is optimally absorbed by the body.

Discover Liposomal Vitamin C, a supplement that benefits from the latest advances in formulation to maximise the many benefits of vitamin C.

Another option is Asc2P (or phosphorylated ascorbate), a rare and stable form of vitamin C that is around 20 times more potent than L-ascorbic acid (the best-known form).

Discover Asc2P Vitamin C, a stabilised, powerful form that is more stable and more bioavailable.

In its classic form (ascorbic acid), vitamin C can cause stomach discomfort. Certain vitamin C food supplements have therefore been developed to suit more fragile stomachs.

Discover Ester C, a vitamin C that respects sensitive digestive mucosa, while offering exceptional bioavailability.

What if the oral microbiota also plays a role?

Several studies link the balance of the oral microbiota to oral health (11-13).

Certain specific probiotic strains could help maintain a good bacterial balance in the mouth (14), and play a part in maintaining oral health.
