Tonsils 101

By | Dental Care | No Comments

Have you ever wondered why we have tonsils? And why it’s sometimes best to have them removed?

If you’re a baby boomer, you might remember that 40 years ago, a tonsillectomy was virtually a rite of passage. Indeed, even earlier, removal of tonsils was actually  fashionable.

But that was then. Let’s look at the facts now and then determine if or when it’s medically necessary to take them out.



Tonsils are oval-shaped masses of lymphatic tissue. Officially, we have five: two are located at the back of the throat—known as “palantine tonsils”, and two sit on the base of the back of the tongue. The adenoid, often considered a separate tissue, is in fact also a type of tonsil. It lies in the back of the nose.


For general purposes, however, we normally think of “tonsils” as those at the back of the throat.

The role of Tonsils in Fighting Infection


You might have heard that tonsils are “vestigial”, meaning our bodies don’t need them at all. Not true. Although medical professionals have a divided opinion about their effectiveness, they clearly do play a role in our immune system by defending the body against infection.

As part of our extensive lymphatic  structure, their strategic location allows them to act as a filter, trapping bacteria and viruses entering the body through the mouth or nose. They also produce lymphocytes and antibodies to fight infection.

However, the jury is still out on whether these small tissues ultimately help or hinder our bodies’ immune system.



Swollen and Diseased Tonsils

Tonsils are most active before puberty, which explains why so many kids get chronic sore throats accompanied by fever. Unfortunately, tonsils can easily get swamped by incoming bacteria and viruses and eventually, become overwhelmed. The result? Rather than fighting infection, tonsils get infected themselves. Tonsillitis then occurs.

Symptoms include:

  • pain or discomfort when swallowing
  • fever, sore throat and swollen glands in the neck

Once your tonsils are diseased, due to tonsillitis or other causes, they are ineffective in fighting infection and can lead to complications.



Complications of tonsillitis run from the merely unpleasant to the seriously dangerous. They include:

  • enlarged tonsils
  • disrupting breathing, swallowing, and sleep (sleep apnea)
  • recurrent or chronic throat and ear infections
  • bad breath
  • strep throat
  • tonsil abscesses (tonsillar crypts) and pockets of pus on the tonsils (peritonsillar abscesses)
  • tonsil stones (tonsoliths)
  • spread of infection from the tonsils into the bloodstream (sepsis)
  • tonsillar cancer—although a rare complication—can occur

Reasons to get a Tonsillectomy


A tonsillectomy generally refers to the removal of the palatine tonsils—those at the back of the throat.

According to the American Academy of Otolaryngology–Head and Neck Surgery (, definite indications for a tonsillectomy include:

  • enlarged tonsils causing upper airway obstruction,
  • severe pain or difficulty when swallowing
  • sleep apnea and associated cardiopulmonary dysfunction
  • tonsillitis causing childhood convulsions due to high fever
  • peritonsillar abscesses that are unresponsive to conservative treatment or drainage
  • need for a tonsillar biopsy

One of the most interesting recent studies about tonsillectomies and sleep apnea involved Louisiana State University, which reviewed studies of children suffering from sleep apnea, about a third of whom also had bedwetting problems. After these children had their tonsils removed, the rate fell significantly, with only about 16 percent still having bedwetting issues, leading researchers to believe there is some relationship between nighttime bedwetting and sleep apnea.


More indefinite—but no less notable—signals for a tonsillectomy include:

  • three or more cases of tonsillitis per year
  • persistent bad breath due to tonsillitis
  • chronic or recurrent tonsillitis in a person who continues to harbor group A strep in the throat (streptococcal carrier ) even after an appropriate antibiotic course
  • formation of an unknown mass (neoplasia)

Although a tonsillectomy is a very common — and simple — operation these days, the surgery is more painful in adults than in children.

Dental Opinions about Tonsils

Now that dental professionals consider a holistic approach to dental and oral care, many hear about tonsils and adenoids because they can create breathing, sleep, jaw development, and other oral problems for their patients.

Dentists are sometimes asked whether removal of tonsils and adenoids will eliminate factors that are contributing to a child’s abnormal jaw and bite development. The answer is problematic, since both sets of tissues may shrink over time, thus improving airway flow, resulting in improved oral development.

However, surgery is a medical rather than a dental issue, and a qualified dentist will refer the patient to a physician for professional advice.

Did you know that the term “tooth decay” is actually one and the same as our childhood fear that our parents threatened us with getting if we ate candy… cavities? This tooth problem is actually on the rise in our society, today.  In this article you will learn its causes, but also learn some ways that we can prevent this type of infection.

The main cause of tooth decay and cavities is bacteria that is left unattended to grow in the mouth. The way that this bacterium causes so much damage is by creating an acid that eats away at the tooth surface (enamel).  By slowly dissolving the enamel on your teeth, plaque then has the ability to form and grow.  The build up of plaque starts creating holes in teeth because minerals are stripped away from the outer layer of enamel. This is basically the first stage of a cavity, but if the present bacteria- acid mixture reaches the next layer of teeth, the dentin, a larger problem will occur.

The dentin is the second defense before getting down to the tooth pulp, which is where all the nerves and blood vessels are contained (that’s when the decay starts to hurt). When the dentin becomes infected it can lead to inflammation, then the worst-case scenario, a pulp infection. The dentin is a much softer, more malleable layer of the tooth than the enamel, and so it is vital to take proper care of it.

Unfortunately there are some dental conditions that can add stress to the teeth and also cause tooth decay. Some of these are tooth grinding, dry mouth conditions where the mouth does not produce enough saliva, or poorly formed enamel. The good news about these conditions is that if treated by a dentist they will not become harmful. Truly, however, frequent dental visits and care are significant to prevent tooth decay and to achieve overall mouth health.

The most beneficial thing you can do to counteract tooth decay is to keep your mouth clean by perfecting your daily dental habits. For basic care it is necessary to brush teeth at least twice a day, and preferably after meals. It is also very important to floss; both of these steps will not allow build up and obviously fight off bacteria in the mouth.

Our diets are also important for a healthy mouth. Today we eat more and more foods that are high in sugar, flavorings, colorings, and processed chemicals. The issue with this modern day diet is that we are missing essential nutrients that support healthy teeth and bones, and allow further risk of breakdown, as sugar especially is a main cause of cavities. To counteract this problem, increase the intake of super foods like milk and green vegetables that provide nutrients and help the teeth to slowly grow stronger.

Keep in mind that even with good brushing and flossing habits and a healthy diet, regular dental visits are a must! Dental cleanings clear plaque from your mouth, but also clean harder to reach areas that we may miss. We don’t know decay is forming until we feel it!

As you can see, the prevention of tooth decay is something that is totally manageable with a little bit of effort. Simply examining your daily dental health, keeping conscious of your diet, and becoming friendly with your dentist can make a significant change for the better, and keep your smile beautiful for years to come!
