When you’ve undergone a
thorough teeth whitening at London dental practices,
the end result can be a killer smile and the radiant confidence associated with
it. Do you know that even with that, some factors can ruin it all?
Genes
and aging
The whiteness of your teeth
is determined by the thickness of your enamel, which is the protective coating
for your dentin (the next layer that is naturally yellowish). This trait can be
inherited and explains why some people have whiter teeth than others. Since
enamel gradually wears down as you grow old, being born with thinner enamel
means your dentin is more likely to show through earlier.
Tobacco
Nicotine in tobacco is a
colourless substance that turns yellow when exposed to oxygen. When tobacco
smoke is inhaled, nicotine—along with tar—percolates the enamel’s microscopic
openings and settles there, resulting in yellowish or brownish teeth. They are
on the outer layer though, so brushing after smoking can help remove them.
Fluoride
overdose
Fluoride helps keep the
teeth healthy, but in excessive quantities, it can break down your teeth’s
enamel. This condition is called fluorosis, which usually results in chalky
white or brown patches or lines on the teeth’s surface. You can shift to
fluoride-free mouth cleaner or use a fluoride product once or twice a week to
reduce consumption.
