Toothpastes can help remove dental plaque. Their various
functions depend on the active ingredients they contain.
There are many different types of toothpaste available in the market.
The followings are the common types of toothpaste: Fluoride toothpaste,
desensitizing toothpaste, anti-calculus toothpaste, anti-plaque toothpaste,
and whitening toothpaste. Their various functions depend on the active
ingredients they contain.
They contain Sodium Fluoride(NaF), Stannous Fluoride(SnF2), or Monofluorophosphate(MFP2).
The fluoride content is about 1,000 parts per million (ppm). They are
all effective in preventing dental caries. Children toothpaste contains
500ppm fluoride and is usually fruit flavoured, which is suitable for
The active ingredients help seal off the microtubules inside the exposed
dentine (such as exposed root surface due to toothbrush abrasion) to
tooth sensitivity. Active ingredients such as Potassium Nitrate are used
by different product manufacturers. There are many different types
of desensitizing toothpastes marketed by different brand names. Their
various functions depend on different active ingredients they contain.
Therefore, you are advised to consult the dentist and undergo a thorough
check-up to explore the cause of tooth sensitivity before using desensitizing
toothpaste. You should consult the dentist if the symptoms of tooth
sensitivity persist after using desensitizing toothpaste. Desensitizing
toothpaste is not suitable for children.
The manufacturer claims that the calcification of dental
plaque could be retarded by this kind of toothpaste, thus it reduces
the rate of calculus formation. The active ingredient is Pyrophosphate
or Zinc Citrate.
This kind of toothpaste inhibits plaque accumulation, reduces the toxic
effects of the bacterial toxin on the periodontal tissues, thereby reduces
the chances of getting periodontal disease. In the market, different anti-plaque
toothpastes contain different active ingredients. For example, Triclosan
or Zinc Citrate.
This kind of toothpaste contains relatively coarse abrasives which function
by abrading the stains on the tooth surface, giving a whitening effect.
However, long term use will result in roughened tooth surfaces, which
makes stains deposit more readily.
Fluoride is effective in the prevention of dental
caries. Since we are all susceptible to dental caries, we all need
Children should use children toothpaste which
contains a lower concentration of fluoride. This can prevent them
from ingesting fluoride accidentally.
Desensitizing toothpaste should only be used when
there is tooth sensitivity. It is not recommended for long-term use.
Hence, we should consult our dentists before using it.
Unless it is under the dentist's supervision,
we should not use whitening toothpaste. Long-term use of whitening
toothpaste will roughen the tooth surfaces, and stains will deposit
on tooth surfaces more readily.
A pea-sized blob of toothpaste is adequate.
When minerals are lost from the surfaces of the
tooth, and a cavity is not formed yet, an appropriate amount of fluoride
can promote the remineralization (redeposit the lost minerals) of
the tooth and repair early dental caries.
Fluoride strengthens teeth, and increases their
resistance to acid attacks.
Fluoride inhibits the growth of dental plaque
and reduces its acid-producing capability.
