Healthy Teeth, Healthy You!

What is the impact of your oral health on your overall health, and why must you be diligent about your oral hygiene?

The health of your mouth often mirrors the condition of your body as a whole. If you are generally healthy, your mouth will reflect that. Conversely, if you have poor oral health, that will directly impact on your body condition.

The link between gum health and other diseases

Research has shown that there is a direct link between gum (periodontal) disease and heart health. If you have active periodontitis, you are at increased risk of developing heart disease.

Severe gum disease in women has also been shown to be correlated to an increased risk of pre-term delivery and giving birth to a low birth-weight baby.  New research constantly shows links between poor gum health and its association with other diseases.

How your mouth can give you clues about your health

Many health complications or diseases can have oral manifestations such as dry mouth, swollen gums and mouth ulcers . Your dentist may be able to pick up early stages of health concerns at your regular dental check-up.


This is a compelling reason to maintain your oral health and hygiene. Ensure that you brush twice daily, floss once daily and visit your dentist every 6 months to maintain tip-top oral hygiene so as to minimise health risks.

Teeth Christmas

Energy drinks and your Teeth

Recently, I came across a patient with severe erosion of her teeth, and that prompted me to write an entry about it. “Jane” is in her thirties and has had a history of drinking energy drinks, which was the cause of her dental erosion.

What are energy drinks?

Energy drinks contain caffeine for a stimulatory effect, and some can also contain other additives, such as vitamins, herbal supplements, and guarana, a plant product that contains concentrated caffeine. These drinks claim to give you a boost in energy levels, help you with alertness and improve concentration. The most well known brand is Red Bull.

Why are energy drinks a problem?

While the caffeine level in each individual drink is relatively low, there is concern when multiple drinks are drunk in a short time, or consumed along with other products containing caffeine, such as caffeine tablets or coffee. These drinks are also particularly marketed to the younger audience, and there is concern over the effect of high doses of caffeine in this age group, particularly children and adolescents.

A common trend for young people, particularly university-age kids, is to mix energy drinks with alcohol. The stimulatory effect of the energy drinks masks the sedative effect of alcohol, allowing more consumption of alcohol. This combination can have adverse, even lethal effects.

So what is the impact on your teeth?

Energy drinks contain high levels sugar levels, and are highly acidic. If drunk frequently, the high acid levels erode your tooth enamel (hard protective layer of the tooth). As a consequence, teeth are much more susceptible to sensitivity and tooth decay.

Back to Jane…

At her dental appointment, we found that many of Jane’s teeth had suffered severe enamel erosion, and she reported that her teeth often felt very sensitive. Three of her teeth had cracked due to loss of the protective enamel layer, needing fillings and dental crowns.

We thoroughly discussed the effect of energy drinks on her teeth, and she has now steered clear of them completely. Unfortunately, the changes are irreversible, and Jane may have further dental problems down the track.

Take home message:

  • Stay away from sugary drinks, especially energy drinks.
  • If you have to drink them, do so through a straw. Dilute them and limit your intake.
  • After drinking, rinse your mouth out with fluoridated tap water to neutralise the acid
  • Wait an hour for the acid to neutralise before brushing your teeth

Common Questions asked:

Are there harmful effects of the bleach on my teeth?

Whitening products are perfectly safe if used correctly according to your dentist’s instructions, and have no long-term adverse effects on your teeth. Sensitivity is a common side effect during treatment. Avoid eating or drinking cold foods for the short time during and after whitening  treatment. Use a sensitive toothpaste for relief, and the sensitivity will eventually disappear over time.

What do I have to avoid when I have just had my teeth whitened?

It is best to avoid food that stain heavily, as well as beverages such as coffee and tea. Allow a few days for the teeth to re-hydrate before resuming your normal diet.
