Question: How are cavities detected by a dentist?
Answer: There are multiple ways a dentist can screen for and detect cavities or tooth decay:
1. Visual- The dentist looks for unusual discolorations, stains and dark spots found along different surfaces of the tooth. The most obvious occur along the biting surfaces of the teeth and are found more commonly on the molars.
2. Feel- The dentist uses an instrument called an "explorer" trying to feel for "stickiness" or catches along the surface of the tooth. The stickiness is often found along the grooves and fissures of the tooth and represents an area where the enamel coating of the tooth has been compromised.
3. Xrays- Digital xrays allow a dentist to see cavities not only along the biting surfaces but the flossing surfaces between the teeth. Not only do xrays provide insight to the presence or absence of a cavity, but it can convey the extent or depth of the cavity. A dentist can use xrays to determine how deep the cavity is and if there is nerve involvement.
4. Laser- Using a device called a "Diagnodent", a dentist can use a special laser that measure the damage that is left behind as a result of cavity or tooth decay. While this is not a primary means of detection, it will typically reinforce the presence of absence of a cavity if there is suspicion.
So the next question is, if there are multiple ways a cavity can be detected, what is the best way?
While there are many ways to detect tooth decay, one way is not more advantageous than the other. Simply put, the dentist should use as many ways as possible to help assess. All four ways can give the dentist tremendous insight into cavity assessment and provide the patient confidence that nothing was missed during an exam!
Question: Hi there, I am a 51 year old woman in pretty good health. In 2004 I had my 4 front teeth removed and porcelain crowns put in. It has become apparent that they were not sealed well enough, so over time decay has set in behind the crowns. They must now be removed and new ones inserted. My financial situation has changed considerably since then and the insurance I have now only covers porcelain infused over metal crowns. It would cost me another $600 per tooth if I want porcelain. I had never heard of these other ones so I would like your input on the aesthetics and longevity of the porcelain infused over metal.Thank you for your time and opinion
Answer: The porcelain fused to metal(PFM) crowns have been around much longer than all porcelain crowns. They are known for strength and I typically do these on back teeth. They do work well on front teeth but can be more challenging to make them look esthetic. I would talk with your dentist about doing the PFM crowns but it will be much more difficult to match the esthetics that you had with all porcelain crowns. I like the all porcelain better but if done correctly the PFM crown can be acceptable as well. My biggest concern is that if they are designed corrected or even if your gums even slightly recede, you can possibly see dark line or metal hue around where the gum has receded. If you have ever seen someone smile and you see a dark color or gray hue around the gum, it is likely it is PFM crown. With an all porcelain crown, even with recession it is not as visible. All porcelain is typically my choice, if and only if your bite will allow it.

What is a cavity(tooth decay)?
Tooth decay is the process that results in a cavity (dental caries). It occurs when bacteria in your mouth make acids that eat away at a tooth. If not treated, tooth decay can cause infection and tooth loss.
You can easily prevent tooth decay by brushing and flossing your teeth regularly, seeing your dentist for teeth cleaning and checkups, and avoiding foods that are high in sugar.
What causes tooth decay?
The combination of bacteria and food causes tooth decay. A clear, sticky substance called plaque that contains bacteria is always forming on your teeth and gums. As the bacteria feed on the sugars in the food you eat, they make acids. The acids attack the teeth for 20 minutes or more after eating. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.
What are the symptoms of tooth decay?
Tooth decay usually does not cause symptoms until you have a cavity or an infected tooth. When this occurs, a toothache is the most common symptom.
How is tooth decay diagnosed?
Your dentist diagnoses tooth decay by:
* Asking questions about your past dental and medical problems and care.
* Examining your teeth, using a pointed tool and a small mirror.
* Taking X-rays of your teeth and mouth.
How is tooth decay treated?
Treatment for tooth decay depends on how bad it is. You may be able to reverse slight tooth decay by using fluoride. To fix cavities caused by mild tooth decay, your dentist will fill the cavities with another substance (fillings). For more severe tooth decay, you may need a crown or root canal. In extreme cases, your dentist may have to remove the tooth.
