Dental Myths Debunked

In General Dentistry January 5, 2019

When it comes to dental health, there are many ideas floating around the Internet and the general “zeitgeist” about the proper care and treatment of your teeth and gums. However, many of these remedies and so-called hacks are usually offered by people who know little to nothing about dental care. While some dental health myths are harmless, there are others that—if adhered to—can cause serious damage to your mouth, teeth, and gums.

Here are some of the most common dental myths and the facts behind them:

MYTH: Invisalign is a substitute for braces

The Internet is full of articles claiming that Invisalign performs the same function as traditional metal braces. While both can effectively correct tooth alignment issues, determining which treatment is best depends on more than just the price tag. Metal braces are used to treat many complex orthodontic issues such as crooked or crowded teeth, protrusions, and irregular spacing. Additionally, Invisalign may not be recommended for patients who have certain health conditions. Discuss your options with your dentist; they will consider important factors like your overall wellness and the specific concern that needs to be addressed.

MYTH: If your teeth are white, they are clean and healthy

Yellow teeth are often associated with poor dental hygiene. However, the natural colour of teeth is not as white as you think. Enamel has a translucent bluish-white tinge that allows the dentin to show through, often giving a smile a slightly yellow shade.

Age also affects tooth colour. Over time, enamel wears away, making the dentin more visible and giving your teeth a more yellowish hue. (This natural erosion depends largely on genetics.) Also, despite regular brushing and proper oral hygiene, some food and beverages (like wine and tea) can stain teeth.

MYTH: Baby teeth don’t need to be taken care of

People mistakenly believe that baby teeth are less important because they eventually fall out. However, these temporary teeth play an important role that can affect oral health as we age. In childhood, baby teeth help with chewing and language development. They also reserve space for the permanent teeth that will replace them. Since baby teeth are smaller, they are more vulnerable to cavities that, if left untreated, can lead to infection and potential damage to the underlying tooth.

MYTH: Lemon juice is a natural tooth whitener

Many online articles suggest using lemon juice as a home remedy for tooth whitening. However, lemon juice is extremely acidic and can cause irreversible calcium loss (calcium is what gives teeth their white hue). Another common suggestion is to mix lemon juice with baking soda. This is not advised, as baking soda erodes enamel and makes teeth vulnerable to damage and decay.

For whiter-looking teeth, discuss with your dentist which tooth whitening method is best for you. By consulting with a professional, you will protect your teeth from harmful substances—and you will see better results.

MYTH: Flossing creates or widens gaps between your teeth

It may seem as though the natural spaces between your teeth become wider when you floss. However, this is due to the removal of tartar, not an actual change in the size of the gaps. Flossing does not create or widen these spaces, but improper flossing can. Certain flossing mistakes (like cutting through gum tissue or forcing floss between your teeth) can cause the gums to recede and create or widen gaps. Your dentist can demonstrate the proper flossing technique that will keep your gums healthy.

MYTH: Putting aspirin directly on a tooth will get rid of toothache

Holding an aspirin directly against your tooth will not remedy a toothache. Incidentally, doing so can damage gums and other soft tissues inside your mouth. To effectively treat a toothache, swallow the aspirin or anti-inflammatory medicine your doctor recommends instead; it needs to enter the bloodstream to be effective.

MYTH: Sugar damages your teeth

Sugar has long been branded as teeth’s worst enemy. However, sugar does not directly cause tooth decay—acid does. When sugar reacts with plaque on the teeth, acid is produced. This acid attacks the teeth and, if not brushed away, can develop into a cavity. When left untreated, a cavity will further decay and reach the nerves, leading to more serious and complicated conditions.

People who are considered high-risk for oral health problems include:

Pregnant women
Smokers
Diabetics
People with gum disease
People who are prone to cavities, plaque buildup, or tooth decay
People with weak immune systems due to infections

During your twice-yearly cleaning and checkup, your dentist will explain when you should have a follow-up examination.

MYTH: Bad breath is a sign of poor dental hygiene

It is easy to conclude that bad breath (halitosis) is caused by neglecting oral hygiene. However, some people still experience bad breath despite brushing and flossing regularly. Several factors can cause halitosis, including:

Food — Onions, garlic, and certain spices can cause bad breath. After these foods are digested, they enter the bloodstream and then the lungs, affecting breath.
Dry mouth — Saliva cleanses the mouth and removes odour-causing particles. Dry mouth is a condition that decreases saliva production and can therefore contribute to bad breath.
Mouth infections — Surgical wounds after dental surgeries (like tooth extractions) can affect your breath. Other conditions like gum disease, mouth sores, and tooth decay may also cause halitosis.
Medications — Some medications can increase the likelihood of bad breath.

MYTH: Brush your teeth immediately after every meal

Most people were taught to brush their teeth immediately after eating. However, teeth are actually at their most vulnerable after a meal or snack. Acids created by food can cause the protective enamel to erode and weaken teeth. In fact, brushing (even with a soft-bristled toothbrush) can cause damage. Most dentists suggest rinsing with water after eating, and waiting 20-60 minutes before brushing. Additionally, limit brushing to twice a day—once during the day and again right before you go to bed.

Avoid online myths, “old wives’ tales” and “health “hacks” before implementing them on your own; advice should always come from your dentist or hygienist.
