  4. Why Are My Teeth Getting More Crowded Over Time?

Hi! I’m Dr Kim Nguyen, an associate dentist here at Pitt St Dental Centre in Sydney CBD.

Yesterday, I had a consultation with a new patient, Samantha from Walsh Bay. She was interested in Invisalign to straighten her teeth. During our session, she asked me, “Hey Kim, my teeth weren’t this crooked before… but it seems like they have gotten worse over the last few years. Are teeth meant to get crowded over time?”

It’s a common question that we get from our Invisalign patients. So I decided to make this short video to help you understand why teeth can get more crowded over time.

So as we grow older, it’s natural to observe subtle changes in our bodies, and this is also the same with our teeth. The noticeable crowding of teeth over time can be attributed to several factors.

As we age, our teeth naturally undergo changes. Over time, they can wear down and become shorter, resulting in a decrease in the overall size of our dental arch. This reduction in space can lead to teeth becoming crowded and potentially overlapping each other over time.

Another interesting theory revolves around how our bodies grow as we age. There’s a forward and downward growth pattern, causing teeth to migrate slowly towards the front. This movement may trigger crowding, particularly noticeable in the lower front teeth.

Here’s something else to keep in mind, if you had orthodontic treatment as a teenager, maintaining a straight smile in the long term depends on your dedication to using retainers. Our teeth have a tendency to shift back to their original positions, and if we don’t stay consistent with wearing our retainers, guess what happens? Crowded teeth can gradually make a comeback. So, it’s important to stay on top of using your retainers to preserve that beautiful straight smile you worked hard to achieve.

Now, crowded teeth isn’t merely an aesthetic issue. They pose an increased risk for dental decay and gum disease, interfere with proper tooth function, and may even impact your confidence by altering your smile. So if you find your teeth are getting crooked or crowded overtime, it would be a good idea to consult your dentist.
