Fillings - Dental


Your dentist may use several methods to determine if you have tooth decay, including
  • Observation — Some discolored spots on your teeth may indicate decay, but not all of them. Your dentist may use an explorer, a metal instrument with a sharp tip, to probe for possible decay. Healthy tooth enamel is hard and will resist pressure by the explorer. Decayed enamel is softer. The instrument will stick in it slightly. Explorers must be used with caution. Pressing too hard with an explorer can damage a healthy tooth.
  • Cavity-detecting dye — This can be rinsed over your tooth. It will stick to decayed areas and rinse cleanly from healthy ones.
  • X-rays — X-rays can help your dentist see decay that doesn't show on the surface. However, X-rays are often not accurate in detecting smaller cavities on occlusal (top) surfaces. Current fillings or other restorations also may block the view of decay.
  • Laser fluorescence cavity detection aids — These small wands measure changes caused by caries (tooth decay). They are especially useful for pit and fissure areas.

Tooth Sensitvity


Tooth sensitivity is a common name for dentin hypersensitivity or root sensitivity. If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful then you have sensitive teeth.
Is Tooth Sensitivity Common?
Tooth sensitivity is very common and it has been estimated that approximately half the population experiences tooth sensitivity. Tooth sensitivity can come and go over time.
Why does Tooth Sensitivity (Dentin Hypersensitivity) Happen?
Tooth sensitivity is usually caused by dentin on root areas exposed due to receded gums or periodontal disease. Receded gums are very common and up to four fifths of people have gum recession by the time they are 65.
When the root of a tooth becomes exposed it does not have a layer of enamel like the crowns of your teeth. Instead the roots have a very soft covering called cementum, which once lost leaves the dentin of the root exposed. Overzealous brushing or using a very abrasive toothpaste can also cause abrasion of the tooth's enamel surface and expose dentin. A very acidic diet – for example a diet with a lot of citrus food, pickles or sodapop — can cause tooth erosion and dissolve the tooth surface, exposing the dentin. Bulimia and GERD can also result in dental erosion and sensitivity due to acid in the mouth.

Keys to Controlling Bad Breath


If you're serious about learning what's causing your bad breath, consider scheduling an appointment with your dental professional. Given your full medical and dental history along with an oral examination, your dentist should be able to identify the culprit. The causes of bad breath are numerous and include certain foods, alcohol or cigarettes, poor oral hygiene, periodontal disease, diabetes, dry mouth, sinus or throat infections, lung infections or abscesses, kidney/liver failure, gastrointestinal issues and severe dieting.
Treatment of Bad Breath
It is important to conduct thorough oral hygiene at home twice daily utilizing tooth brushing with a fluoride antibacterial toothpaste and flossing to remove food debris and plaque on teeth, bridgework and implants, and brushing the tongue to remove odor-causing bacteria. A published study reported that tongue and tooth brushing in combination with dental flossing significantly decreased bleeding of the gum tissue over a two week period of time as well as reduced bad breath1. Another clinical study conducted by the University of Buffalo dental researchers confirmed that brushing twice a day with an antibacterial toothpaste and using a tooth brush with a tongue cleaner can eliminate bad breath 2.

Bad Breath


Bad breath, also known as halitosis, is breath that has an unpleasant odor. This odor can strike periodically or be persistent, depending on the cause. In many people, the millions of bacteria that live in the mouth (particularly on the back of the tongue) are the primary causes of bad breath. The mouth's warm, moist conditions make an ideal environment for these bacteria to grow. Most bad breath is caused by something in the mouth.
Some types of bad breath, such as "morning mouth," are considered to be fairly normal, and they usually are not health concerns. The "morning mouth" type of bad breath occurs because the saliva that regularly washes away decaying food and odors during the daytime diminishes at night while you sleep. Your mouth becomes dry, and dead cells adhere to your tongue and to the inside of your cheeks. Bacteria use these cells for food and expel compounds that have a foul odor.

Burning mouth syndrome


Burning mouth syndrome causes chronic burning pain in your mouth. The pain from burning mouth syndrome may affect your tongue, gums, lips, inside of your cheeks, roof of your mouth, or widespread areas of your whole mouth. The pain can be severe, as if you scalded your mouth.
Unfortunately, the cause of burning mouth syndrome often can't be determined. Although that makes treatment more difficult, don't despair. By working closely with your health care team, you can usually get burning mouth syndrome under control.
Other names for burning mouth syndrome include scalded mouth syndrome, burning tongue syndrome, burning lips syndrome, glossodynia and stomatodynia.
Symptoms
Symptoms of burning mouth syndrome include:
  • A burning sensation that may affect your tongue, lips, gums, palate, throat or whole mouth
  • A tingling or numb sensation in your mouth or on the tip of your tongue
  • Mouth pain that worsens as the day progresses
  • A sensation of dry mouth
  • Increased thirst
  • Sore mouth
  • Loss of taste
  • Taste changes, such as a bitter or metallic taste

Dental Crowns and Tooth Bridges

What are Dental Crowns and Tooth Bridges?
Both crowns and most bridges are fixed prosthetic devices. Unlike removable devices such as dentures, which you can take out and clean daily, crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.
How do Crowns Work?
A crown is used to entirely cover or "cap" a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the color of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.
