A 2008 study found that the
whiteness of a person’s smile played a role in the way others perceived them.
Specifically, the study found that people with white teeth were perceived to be
more attractive and smarter than people with darker teeth.
Bad Breath
Bad breath
is usually caused by:
·
poor oral care habits
·
tooth infection
·
gum disease
·
mouth sores
·
infection or chronic inflammation of the nose or throat
·
smoking
·
dry mouth, which may be a side effect of some medications
·
certain foods, like garlic or onion
The best
ways to combat bad breath is to stay hydrated, floss daily, and brush your
teeth twice per day. Don’t forget to brush your tongue, too!
If you
wear dentures or other mouth appliances, clean them daily. Use an alcohol-free
mouthwash and artificial saliva or a spray or gel for dry mouth.
If your
breath suddenly takes on an unpleasant or unusual odour, it may be a sign of a
serious disorder, such as diabetes or a bowel obstruction. If this occurs, you
should seek medical attention immediately. Chronic dry mouth that’s unrelated
to medication use should also be investigated because it may indicate an
autoimmune condition or other disorder.
Proper
brushing and flossing will keep your gums healthy. Periodontal, or gum, disease
is an infection of the tissues that surround and support your teeth. This type
of infection is caused by a build-up of plaque, which is a sticky film of
bacteria that forms on your teeth.
Gum disease is often painless, but it makes gums red and puffy and
causes them to recede and bleed. The infection can progress over time leading
to more serious symptoms. In fact, gum disease is a major cause of tooth
loss in adults.
The good
news is that gum disease is almost always preventable. Regular check-ups with
your dentist combined with good oral hygiene, which means brushing and flossing
twice daily, can keep plaque at bay.
Many
over-the-counter (OTC) toothpastes, mouth rinses, and chewing gums claim to
have a whitening effect. You can also speak with your dentist about
prescription whitening treatments or in-office treatments.
Proper
Dental Hygiene
The
easiest thing to try at home is simply following proper dental hygiene. That
means using fluoride toothpaste and flossing every day. Many people can also
benefit from mouth rinses.
You may be
interested in trying a whitening toothpaste. Whitening toothpastes contain mild
abrasives that can help remove stains. However, whitening toothpastes cannot
change the colour of your teeth because they only remove stains on the surface.
Bleaching
Agents
Dentin is
the bony tissue forming the bulk of the tooth under the enamel. The thickness
of the enamel layer changes throughout our lives and gets thinner as we age.
The thinner the enamel, the more yellow your teeth appear as the dentin layer
dominates the final shade.
If your
dentin has a yellowish tint, you’ll need to use a peroxide-bleaching agent to
lighten the colouring. This, in turn, can help make your teeth appear whiter.
Some
bleaching agents are available over the counter, such as paint-on whiteners or
whitening strips. These are relatively cheap and effective. Be sure to look for
a product that is at least 6 percent bleaching agent.
OTC
treatments may not be effective if you have:
·
isolated stains, such as a single discoloured tooth
·
dark stains
·
crowns
·
dental implants or other restorations
You should
consult a dentist to discuss your options. Dentists can prescribe bleaching
kits for home use, or they can bleach your teeth in the office. This typically
involves applying a bleaching agent to your teeth and then using a special
light or laser to enhance the effect of the whitening agent.
The jury
is still out on the safety of the bleaching process and whether the bleaching
agent might be toxic if ingested. Long-term use of bleaches or abrasive
toothpastes can increase sensitivity or gum irritation. If your teeth are
sensitive to hot or cold, you may want to avoid whitening agents.
Bleaching
During Pregnancy
While both home and prescription products can be considered safe at this
time, you should not have a bleaching procedure during pregnancy. The American Pregnancy Association (APA) recommends
postponing all unnecessary dental work, including whitening procedures, until
after birth to prevent exposing the foetus to potentially dangerous chemicals
or medications.
Straightening
crooked teeth can also have an effect on your smile. Some adults are candidates
for Invisalign, which uses transparent trays, or aligners, to straighten the
teeth.
If you
have bite problems or more complex orthodontic issues, you may need traditional
braces. Brackets made of tooth-coloured ceramic or polycarbonate are less
noticeable than stainless steel brackets. Sometimes, the brackets can be
mounted on the back surface of the teeth.
A missing,
chipped, or stained tooth can be replaced with a crown or dental implant, which
is an artificial tooth permanently anchored into the bone of the jaw. Porcelain
veneers are pricey, but they can transform your smile after just a couple of
visits to your dentist. See a cosmetic dentist to discuss your options.
Speak with Your Dentist
If you’re
interested in improving your smile, speak with your dentist. They can recommend
treatments you may want to try. Your dentist can also help you understand what’s
covered if you have insurance.
