Why do i get cavities (holes) despite cleaning my teeth well?

Bacteria and sugar!

Well, the bottom line is that cavities in teeth are caused by bacteria. Your mouth is full of good and bad bacteria. The balance between them is key. Food that contains plenty of sugar can tip that balance in favour of the bad bacteria. This can result in significantly more cavities. Sugar is almost in everything nowadays. As part of our dental checkup appointment, we often educate our patients in the importance of looking at the sugar content available at the back of the packaging. They appear in things like yoghurt, cereal, muesli bars and much more. 

Cleaning well

On the topic of cleaning- flossing is an important aspect of that. Brushing alone is not sufficient to clean your teeth. When you chew, food will get lodged between your teeth and a toothbrush is not designed to remove food in between your teeth. This is where flossing or interdental brushes come into play. More recently, water floss is a popular option for those who find flossing difficult. 

Genetics

One last aspect to consider is the quality of your teeth and saliva. Some people are blessed with very strong teeth and plenty of saliva with a good buffering capacity which helps prevent cavities. On the other hand, others have very thin/ weak teeth and low amount of saliva which results in more cavities. So yes- GENETICS do play a part in all of this. We find the best way of preventing cavities is having a good oral hygiene routine including brushing and flossing. In addition, always be smart about what you eat and drink and to have professional checks and cleans twice a year.
