Are Your Teeth Getting Long?

Are your teeth starting to look longer as you age? 
Long appearance of teeth due to aggressive brushing
Ever hear the phrase “long in the tooth?”  Well, this phrase was originally used to refer to older people and horses.  Unlike humans, horses teeth continue to grow as they age, which indicates that horses with long teeth are older.  However, human teeth don’t continue to grow with age, but they can appear to look longer as people age.  There are many factors that can explain why teeth appear to lengthen as people age….

·        Gum Recession –  causes of gum recession are as follows…

o   Vigorous Hygiene (bushing too hard)

o   Bruxism – or grinding your teeth (which can also shorten teeth)

o   Extensive orthodontic treatment

o   Trauma – such as an accident

·        Periodontal Disease – In the advanced stages of gum disease, or gingivitis.  This is an infection in the gums and underlying bone.  When left untreated, bacteria begins to destroy the underlying bone and gum tissue leaving teeth mobile, or wiggly, while exposing the root of the tooth. Over 70% of Americans have some form of gum disease.  This can only be treated by your dentist.  This is also the number cause of premature tooth loss and can cause many health concerns, including cardiovascular problems.

·        Habits

o   Chewing ice

o   Smoking or using smokeless tobacco

o   Certain recreational drugs 

It was once thought that losing our teeth was part of the natural aging process.  However, we now know that with proper care, healthy habits, healthy diet and regular dental visits premature tooth loss can be a thing of the past. If you have noticed you are starting to get “long in the tooth” talk to your dentist about your options. Dentistry has come a long way and there are many options to help you maintain a youthful smile for your entire life!

Why Cold Foods Make Teeth Hurt

One of the most frequent questions I get is about sensitive teeth. There are many potential reasons for sensitivity. Sometimes this could be a minor nuisance, whereas in other cases, this could be much more serious.

Here are a few reasons for cold sensitivity:
  • Metal restorations: Many people have fillings, crowns, bridges and other metallic restorations. The reason why there is often cold sensitivity with these types of restorations is that metal conducts temperature rather well. So any temperature change will trigger pain receptors within the tooth.
  • Gum recession: When gums recede, the root surfaces of the teeth become exposed. Exposed root surfaces can be very sensitive to cold because there is no enamel covering the surface.
  • Decay: A surface that has decay is often cavitated. The break in the continuity of the enamel makes the tooth much more sensitive to cold.
  • Teeth with enlarged pulps: There are nerves and blood vessels inside every tooth. The space within the tooth that they occupy are called the pulp. Younger people have larger pulps. As we age, the space gets smaller. This means that the pulp of younger teeth are closer to the surface of the tooth. In other words, there is less tooth structure insulating the tooth. So in the absence of other issues, younger teeth are more likely to be sensitive to cold.
  • Temporary restorations: Temporary restorations simply do not fit as well as permanent restorations and are very likely to be cold sensitive. Click here to see a previous blog on temporaries.
  • "High" restorations: When you bite down, if there is a spot on a tooth or restoration that makes premature contact, it will cause more force to be applied to the tooth repetitively. The extra force on a single tooth will make it become sensitive to biting pressure. In addition, the tooth will also become more sensitive to cold. Fortunately, this can be fixed easily. A small amount of restorative material may just need to be polished away to decrease the biting pressure.
  • Defective restorations with open margins: If there is a gap in the interface between the restoration and a tooth, cold sensitivity is likely to become an issue. This is because of two things. The first is that there is simply a gap and the exposed tooth structure is quite sensitive. The second reason is that bacteria migrate into the spaces and infect the tooth structure. The decay that occurs is very toxic to the pulp. When the pulp becomes infected, the nerves become hypersensitive.
  • Trauma: When there is trauma to a tooth, the nerves and blood vessels within a tooth become inflamed. Since they are in a confined space with no room to expand, the pulp becomes incredibly hypersensitive.
  • Infected pulp: When this occurs, the pain will be intense. The pain may also linger for some time after the source of cold is removed. In addition, the tooth may experience a throbbing sensation.

If you are suffering from cold sensitivity get the advice of your dentist. Do not ignore the problem, because it may lead to more complications.
