The most common side effects
associated with laser speed tooth Whitening procedures & tooth
bleaching treatments
are increased
sensitivity of the teeth and irritation of the gums, which tend to resolve once
the Dental whitening or Dental Bleaching is stopped.
Hypersensitivity
The low pH of bleach opens up
dentinal tubules and may result in dentine hypersensitivity, bringing about
hypersensitive teeth. It manifests as increased sensitivity to stimuli such as
hot, cold or sweet. 67 – 78% of the patient’s experience teeth sensitivity
after in office bleaching with hydrogen peroxide in combination with heat.
Sensitivity of teeth can persist up to 2 days after teeth bleaching cessation.
However, it varies from person to person. A longer duration of hypersensitivity
has been reported 10 days post-bleaching.
Recurrent treatments or use of
desensitising toothpastes may alleviate discomfort, though there may be
occurrences where the severity of pain discontinues further treatment.
Potassium nitrate and sodium fluoride are used to reduce tooth sensitivity
following bleaching.
Irritation of mucous membranes
Hydrogen peroxide is an irritant and
cytotoxic. At concentrations of 10% or higher, hydrogen peroxide is potentially
corrosive to mucous membranes or skin and can cause a burning sensation and
tissue damage. Chemical burns from gel bleaching (if a high-concentration
oxidizing agent contacts unprotected tissues, which may bleach or discolor
mucous membranes). Tissue irritation most commonly results from an ill-fitting
mouthpiece tray rather than the tooth-bleaching agent.
Uneven results
After Dental teeth bleaching or
bleaching of teeth with night trays, it is normal to have uneven results. With
time, the color will appear more even. To avoid this from happening it is
important to avoid making some common post-bleaching mistakes, such as
consuming foods and beverages that stain the surface of your teeth.
Return to original pre-treatment
shade
Nearly half the initial change in
color provided by an intensive in-office treatment (i.e., 1 hour treatment in a
dentist's chair) may be lost in seven days. Rebound is experienced when a large
proportion of the tooth whitening has come from tooth dehydration (also a significant
factor in causing sensitivity). As the tooth rehydrates, tooth color 'rebounds'
back toward where it started.
Over-bleaching
Over bleaching, known in the
profession as "bleached effect", particularly with the intensive
treatments (products that provide a large change in tooth colour over a very
short treatment period, e.g., 1 hour). Too much bleaching will cause the teeth
to appear very translucent.
Damage to enamel
Home tooth bleaching treatments can
have significant negative effects on tooth enamel. Study has been done and
there is evidence that high concentration of carbamide peroxide can damage the
enamel surface. Although the effect on enamel is less detrimental than seen
after phosphoric acid etch, the increased roughness of the surface may make
teeth more susceptible to extrinsic discolouration after bleaching.
Weakened Dentin
Intracoronal bleaching with 30%
hydrogen peroxide decreases micro-hardness of dentin. Thus, weakening the
mechanical properties.
Effects on existing restorations
Dental Amalgam – Exposure to
carbamide peroxide solutions increase mecury release for one to two days.
Resin Composite – bond strength
between enamel and resin based fillings weakened.
Glass Ionomer and other cements –
Study suggesting that solubility of these materials may increase.
Bleachorexia
When bleaching is abused and an
individual develops an unhealthy obsession with whitening, the term
bleachorexia or whitening junky has been used. The condition is characterized
by repeated bleaching even though the teeth are already white and will not get
any whiter. This condition is somewhat similar to body dismorphic disorder. The
individual perceives their teeth never to be white enough, despite repeated
bleaching. A person with bleachorexia will typically continually request more
bleaching services or products from the dental professional. It has been
recommended that a target shade be agreed before starting bleaching treatment
to help with this problem.
Other risks
Hydrogen peroxide might act as a
tumour promoter Intracoronal internal bleaching may also cause cervical root
resorption, it is more commonly observed in teeth that are treated with
thermo-catalytic bleaching method. Due to extensive removal of intracoronal
dentin, tooth crown fracture can happen after intracoronal bleaching.
The International Agency of Research
on Cancer (IARC) has concluded that there is insufficient evidence for the
carcinogeni-city of hydrogen peroxide. The chemical is now under Group 3:
Unclassifiable as to carcinogenicity to humans. The genotoxic potential of
hydrogen peroxide has been evaluated recently. Oral health products that
contain or release hydrogen peroxide up to 3.6% H2O2 is not likely to increase
cancer risk in individuals.
