Acid in Your
Mouthwash Can Be Eroding the Enamel on Your Teeth! |
|
|
|

(and
making them very sensitive) |

Recent research has uncovered a startling new discovery about
the mouthwash you are probably using. Did you know that over
90% of the mouthwash that is commercially available contains
an acid level comparable to that of household vinegar? |
|
| |
 |
|
| |
Can you imagine rinsing and gargling with vinegar?
I don't even have to tell you what that would
taste like, but think for a second what it can do to your teeth! |
|
| |
|
|
| |
The enamel on your teeth is one of the hardest substances that
your body can produce. But acid is one of the most corrosive
substances in nature. The study below which was completed in
April of 2001 discovered that rinsing your mouth with a
mouthwash that contains a high concentration of acid causes a
drastic increase in enamel loss. |
|
| |
|
|
| |
And enamel loss has a direct correlation to sensitivity in teeth
- people with less enamel complained of much greater
sensitivity in their teeth to hot and cold. |
|
| |
|
|
| |
As you can see from the chart below - almost all commercially
available mouthwashes have a highly 'acidic' environment.
But TheraBreath is actually an
'antacid' mouthwash! |

The erosive effects of some
mouthrinses on enamel. A study in situ. |

BACKGROUND: There are both anecdotal clinical
and laboratory experimental data suggesting that low pH
mouthrinses cause dental erosion. This evidence is particularly
relevant to acidified sodium chlorite (ASC) formulations since
they have plaque inhibitory properties comparable to
chlorhexidine but without the well known local side effects. |
|
| |
|
|
| |
AIM: Studies in situ and in vitro were planned
to measure enamel erosion by low pH mouthrinses. The study in
situ measured enamel erosion by ASC, essential oil and
hexetidine mouthrinses over 15-day study periods. The study was
a 5 treatment, single blind cross over design involving 15
healthy subjects using orange juice, as a drink, and water, as a
rinse, as positive and negative controls respectively. 2 enamel
specimens from unerupted human third molar teeth were placed in
the palatal area of upper removable acrylic appliances which
were worn from 9 a.m. to 5 p.m., Monday to Friday for 3 weeks.
Rinses were used 2x daily and 250 ml volumes of orange juice
were imbibed 4x daily. Enamel loss was determined by
profilometry on days 5, 10 and 15. The study in vitro involved
immersing specimens in the 4 test solutions together with a
reduced acid ASC formulation for a period of 4 h under constant
stirring; Enamel loss was measured by profilometry every hour. |
|
| |
|
|
| |
RESULTS: Enamel loss was in situ progressive
over time with the 3 rinses and orange juice but negligible with
water. ASC produced similar erosion to orange juice and
significantly more than the two proprietary rinses and water.
The essential oil and hexetidine rinses produced similar erosion
and significantly more than water. Enamel loss in vitro was
progressive over time, and the order from low to high erosion
was reduced acid ASC, ASC, Essential oil, and hexetidine
mouthrinses and orange juice. |
|
| |
|
|
| |
CONCLUSION: Based on the study in situ, it is
recommended that low pH mouthrinses should not be considered for
long term or continuous use and never as pre-brushing rinses. In
view of the plaque inhibitory efficacy of ASC, short- to
medium-term applications similar to those of chlorhexidine would
be envisaged. |
