Nutritional supplements that may be helpful: A 0.1% solution
of folic acid used as a mouth rinse (5 ml taken twice a
day for 30 to 60 days) has reduced gum inflammation and bleeding in people with gingivitis in
double-blind trials.1 2 The folic acid solution is rinsed in the mouth
for one to five minutes and then spit out. Folic acid was also found to be effective when
taken in capsule or tablet form (4 mg per day),3 though in another trial studying
pregnant women with gingivitis, only the mouthwash—and not folic acid in pill
form—was effective.4 However, this may have been due to the body’s
increased requirement for folic acid during pregnancy.
Phenytoin (Dilantin®) therapy causes gum
disease (gingival hyperplasia) in some people. A regular program of dental care has been
reported to limit or prevent gum disease in people taking phenytoin.5 6
7 Double-blind research has shown that a daily oral rinse with a liquid folic acid
preparation inhibited phenytoin-induced gum disease more than either folic acid in pill form
or placebo.8
People who are deficient in vitamin C may be at
increased risk for periodontal disease.9 When a group of people with periodontitis
who normally consumed only 20–35 mg of vitamin C per day were given an additional 70 mg
per day, objective improvement of periodontal tissue occurred in only six weeks.10
It makes sense for people who have a low vitamin C intake (e.g., people who eat few fruits and
vegetables) to supplement with vitamin C in order to improve gingival health.
For people who consume adequate amounts of vitamin C in their diet, several studies have
found that supplemental vitamin C has no additional therapeutic effect. Research,11
including double-blind evidence,12 shows that vitamin C fails to significantly
reduce gingival inflammation in people who are not vitamin C deficient. In one study,
administration of vitamin C plus flavonoids (300 mg per
day of each) did improve gingival health in a group of people with gingivitis;13
there was less improvement, however, when vitamin C was given without flavonoids. Preliminary
evidence has suggested that flavonoids by themselves may reduce inflammation of the
gums.14
Preliminary evidence has linked gingivitis to a coenzyme
Q10 (CoQ10) deficiency.15 Some researchers believe this deficiency could
interfere with the body’s ability to repair damaged gum tissue. In a double-blind trial,
50 mg per day of CoQ10 given for three weeks was significantly more effective than a placebo
at reducing symptoms of gingivitis.16 Compared with conventional approaches alone,
topical CoQ10 combined with conventional treatments resulted in better outcomes in a group of
people with periodontal disease.17
Some,18 but not all,19 research has found that giving 500 mg of calcium twice per day for six months to people with periodontal
disease results in a reduction of symptoms (bleeding gums and loose teeth). Although some
doctors recommend calcium supplementation to people with diseases of the gums, supportive
scientific evidence remains weak.

Herbs that may be helpful:
Bloodroot contains alkaloids, principally sanguinarine, that are sometimes used in
toothpaste and other oral hygiene products because they inhibit oral bacteria.20
21 Sanguinarine-containing toothpastes and mouth rinses should be used according to
manufacturer’s directions. A six-month, double-blind trial found that use of a bloodroot
and zinc toothpaste reduced gingivitis significantly better
than placebo.22 However, a similar study was unable to replicate these
results.23 Thus, at present, it is unknown who will respond to bloodroot toothpaste
and who will not. Concerns also exist about the long-term safety of bloodroot.
A mouthwash combination that includes sage oil, peppermint oil, menthol, chamomile tincture, expressed juice from echinacea, myrrh tincture, clove
oil, and caraway oil has been used successfully to treat
gingivitis.24 In cases of acute gum inflammation, 0.5 ml of the herbal mixture in
half a glass of water three times daily is recommended by some herbalists. This herbal
preparation should be swished slowly in the mouth before spitting out. To prevent recurrences,
slightly less of the mixture can be used less frequently.
A toothpaste containing sage oil, peppermint oil, chamomile tincture, expressed juice from
Echinacea purpurea, myrrh tincture, and rhatany tincture has been used to accompany
this mouthwash in managing gingivitis.25
Of the many herbs listed above, chamomile, echinacea, and myrrh should be priorities. These
three herbs can provide anti-inflammatory and antimicrobial actions critical to successfully
treating gingivitis.
