Couldn't agree more with Dr Poon. As orthodontists, we do see a greater proportion of patients in their late teens/early 20s coming to see us with regards to overlapping of the lower front teeth in particular. There are many theories for this late crowding, however the treatment options are the same.
Retainers would be the best way to maintain the alignment of your teeth. Many of us grind our teeth in our sleep, the retainers could also function as a nightguard and protect your teeth if you do. If your teeth have shifted, you may want to consider aligning them before making a pair of retainers. If you decide to straighten your teeth later on, you won't be able to wear these retainers anymore, which will be a waste.
Most importantly, make sure you see your general dentist every 6 months to make sure your gums are in tip top condition.
hope this helps!
Warm regards,
