Common Dental Issues You’ll Likely Encounter Before You Turn 30

Given all the gnashing, biting, crunching and chewing that our teeth do on a daily basis, our teeth are surprisingly resilient. Still, daily wear and tear, as well as the natural ageing process, will eventually take a toll if proper dental care is neglected. Also, by the time you hit 30, you will have already gone through several milestones with your pearly whites. Here are some of the common dental encounters you may have experienced so far:

Wisdom teeth

Wisdom teeth are the molars that are located at the very back of your mouth. These teeth usually appear between the ages of 17 to 25. Approximately 80% of the people who have wisdom teeth need to have them removed, as they often have a negative impact on the jaw, surrounding teeth, and bite alignment.



Some people may have gotten their first cavity/cavities when they were kids or as a teenager, while others won’t have any until they hit adulthood. However, by the time you turn 30, chances are you would have experienced at least one cavity.

Unfortunately, regardless of how strict your dental hygiene routine is, cavities can be unavoidable. That being said, you should consult a dentist as soon as you can if there are any cavities that have not been filled yet. If the existing problem persists and there is tooth decay, you might even need a root canal procedure – which is not ideal!


In Australia, more than 60% of kids wear braces between the ages of 10 and 14 years old. However, many adults, who are well past the age of 30, still seek ways to straighten their teeth with braces. This is usually because their bite alignment and teeth have changed over time, or because their parents couldn’t afford to get them braces when they were younger.

Now that Invisalign has taken off in Australia, many adults are now opting for Invisalign over braces to achieve a straighter smile.

Dental Precautions to Take as You Age

First and foremost, you will want to prevent acid erosion. Sugary and starchy food can be a major threat to your dental health, as they contain carbohydrates that can ferment. When this happens, the bacteria in your mouth will start to produce acids that will inevitably eat away at the enamel on your teeth. This creates tiny pits that can lead to tooth decay. This is why it’s important to try and cut down on sweetened, carbonated beverages as much as possible, because carbonation is one of the biggest dietary contributors to acid in the mouth.

You should also take note of how mechanical your teeth functions are. Your teeth mash, grind and break up food into small pieces to make them easier to digest. In most cases, your teeth are resistant to cracks and chips and they do not become more brittle as you age – contrary to what many people assume. You will just need to take note of what you chew on as root canals or dental fillings are more vulnerable to wear and tear, and can result in chipped or cracked teeth, as they’re not as structurally sound and strong as intact teeth.
