Does chewing ice harm my teeth?

Q:

I have a habit of chewing ice, it feels good and relaxes me after a long day. Will this have any long term impact on my teeth? via email Saturday August 21, 2010

A:

Thanks for the question! Chewing ice can be detrimental to your teeth as it is a repetitive force that is applied to your teeth. Ice a hard substance which when chewed between teeth over time can have the potential to cause small fractures on the tooth surface. These small fractures on the surface of the tooth can over time become larger until a piece of tooth actually fractures off.

As well, ice is cold thus the temperature change in the mouth may cause existing fillings in the teeth such as composite (white) or amalgam (silver) fillings to contract and when the ice is taken away to once again expand. When this happens repeatedly, the area between the filling and the tooth can become weaker and allow leakage between the tooth which has the potential to irritate the pulp and nerve of the tooth.

I would recommend trying to stop this as it can be harmful to the dentition. As well, I would suggest you seen your physician as repetitive ice chewing can be related to anemia (low iron levels), this is called Pica.

Have a great day!

Braces for teeth that are crooked

Q:For as long as I can remember my teeth have been crooked and over the years they have seemed to become even worse. I am very unhappy with the look of my smile and thinking about straightening them. I want to do the best thing possible, what do you suggest for crooked teeth? Via email Thurs. August 10, 2010

A:It is hard to answer your question on a whole since I have not examined your teeth in person, but I will provide some answers below which you may explore to see what is the best option for you.The first choice is orthodontics (braces) as these will address the alignment of both your teeth and jaw, thus providing a more harmonious bite and long term aesthetics. Orthodontics are optimally done by an orthodontist who has many years of expertise/training with straightening teeth and ensuring it is done properly. The time span for orthodontics can vary from a short period of time (sometimes less than a year) to multiple years depending on the situation that presents upon examination and x-rays.Another choice is veneers. Veneers are thin tooth coloured shells that are cemented onto the teeth. When teeth are out of alignment, crooked or have small spaces between them, custom made veneers may be permanently adhered to individual or groups of teeth to give the appearance of straight, evenly spaced teeth and smile. Veneers are not an option for everyone and prior to going with this choice the dentist should fully examine and assess whether veneers are a good long term option for your teeth, smile and aesthetics. Veneers do not last forever, the lifespan can be anywhere from 5-10 years and then they will need to be changed to new ones.Regardless of which route you take to straighten your teeth, please see a qualified dentist to assess the right route to go.

Great question!
