Dental Exam and Cleaning
A comprehensive dental exam will be performed by your dentist at your initial dental visit. At regular check-up exams, your dentist and hygienist will include the following:
- Examination of diagnostic x-rays (radiographs): Essential for detection of decay, tumors, cysts, and bone loss. X-rays also help determine tooth and root positions.
- Oral cancer screening: Check the face, neck, lips, tongue, throat, tissues, and gums for any signs of oral cancer.
- Gum disease evaluation: Check the gums and bone around the teeth for any signs of periodontal disease.
- Examination of tooth decay: All tooth surfaces will be checked for decay with special dental instruments.
- Examination of existing restorations: Check current fillings, crowns, etc.
Professional Dental Cleaning
Professional dental cleanings (dental prophylaxis) are usually performed by Registered Dental Hygienists. Your cleaning appointment will include a dental exam and the following:
- Removal of calculus (tartar): Calculus is hardened plaque that has been left on the tooth for some time and is now firmly attached to the tooth surface. Calculus forms above and below the gum line and can only be removed with special dental instruments.
- Removal of plaque: Plaque is a sticky, almost invisible film that forms on the teeth. It is a growing colony of living bacteria, food debris, and saliva. The bacteria produce toxins (poisons) that inflame the gums. This inflammation is the start of periodontal disease!
- Teeth polishing: Remove stain and plaque that is not otherwise removed during tooth brushing and scaling.
This is used to fill in narrow grooves in a tooth that cannot be adequately cleaned by brushing. In some cases, the tooth structure has fine grooves or pits which accumulate plaque, not because the person doesn't brush, but because they're too narrow to allow even one bristle into them. These will develop cavities over time, and you don't want that. So the dental hygienist will brush on a coating that seals the grooves and pits, making it possible to brush off all the plaque and keep your teeth healthy.
Digital radiography (digital x-ray) is the latest technology used to take dental x-rays. This technique uses an electronic sensor (instead of x-ray film) that captures and stores the digital image on a computer. This image can be instantly viewed and enlarged helping the dentist and dental hygienist detect problems easier. Digital x-rays reduce radiation 80-90% compared to the already low exposure of traditional dental x-rays.
Dental x-rays are essential, preventative, diagnostic tools that provide valuable information not visible during a regular dental exam. Dentists and dental hygienists use this information to safely and accurately detect hidden dental abnormalities and complete an accurate treatment plan. Without x-rays, problem areas may go undetected.
Dental x-rays may reveal:
- Abscesses or cysts.
- Bone loss.
- Cancerous and non-cancerous tumors.
- Decay between the teeth.
- Developmental abnormalities.
- Poor tooth and root positions.
- Problems inside a tooth or below the gum line.
Detecting and treating dental problems at an early stage may save you time, money, unnecessary discomfort, and your teeth!
Are dental x-rays safe?
We are all exposed to natural radiation in our environment. Digital x-rays produce a significantly lower level of radiation compared to traditional dental x-rays. Not only are digital x-rays better for the health and safety of the patient, they are faster and more comfortable to take, which reduces your time in the dental office. Also, since the digital image is captured electronically, there is no need to develop the x-rays, thus eliminating the disposal of harmful waste and chemicals into the environment.
Even though digital x-rays produce a low level of radiation and are considered very safe, dentists still take necessary precautions to limit the patient’s exposure to radiation. These precautions include only taking those x-rays that are necessary, and using lead apron shields to protect the body.
How often should dental x-rays be taken?
The need for dental x-rays depends on each patient’s individual dental health needs. Your dentist and dental hygienist will recommend necessary x-rays based upon the review of your medical and dental history, a dental exam, signs and symptoms, your age, and risk of disease.
A full mouth series of dental x-rays is recommended for new patients. A full series is usually good for five years. Bite-wing x-rays (x-rays of top and bottom teeth biting together) are taken at recall (check-up) visits and are recommended once a year to detect new dental problems.
