The importance of Dental Hygiene

The importance of Dental Hygiene Dental office Grimsby

Tooth brushing is one of the most important aspects of good oral hygiene.

Others include flossing, diet, visiting the dentist regularly, etc. Many people question their dentist as to which brand or type of brush is the best to use. Many have personal preferences, however, what is agreed on most, is that a soft brush is best. Medium or hard can cause damage and wear to the soft tissues surrounding the teeth, as well as unnecessary wear to the tooth outer surface called enamel. Brushes should be replaced often, usually after three to four months or after a bad cold or flu. Ideally, one should brush after each meal, but at least mornings and before bedtime should be made part of one’s normal routine.

Other common questions are what types of bristles should a toothbrush have. The answer again depends on personal preference, however, studies have found that synthetic bristles are best due to their ability not to split as often as natural bristles. This splitting of the bristle ends can cause severe gum irritations and eventually recession of the gums and tooth sensitivity. If one uses a synthetic soft-bristled toothbrush that is replaced often, it will not cause this irritation.

Sequence of brushing

Each person has their own method of brushing, however, an easy technique is to divide the mouth into six sections. Depending on if one is right or left handed, you can choose which side to start on in the upper arch. Assuming you start on the upper right, start brushing the posterior four teeth. Place the toothbrush slightly on the gums or gingivae at a 45-degree angle and partly on the tooth. Gently brush back and forth. After brushing in this fashion, move the brush further down away from the gums and onto the rest of the teeth. Go further anteriorly until you reach the next one third. You should now be on the anterior six teeth.

Repeat the procedure. Move on to the four back left teeth, repeating the back and forth motions. Once completed, brush the left four posterior teeth, on the biting or occlusal surfaces. Roll to the inside tongue or lingual side of the teeth. Again, place the brush at a 45-degree angle on the gums and tooth. Follow this procedure now going from left to anterior to right upper back teeth. This is now repeated by dropping down to the lower teeth. Follow the same instructions.

  • The outer/inner surface of teeth: Place your toothbrush at a 45-degree angle against your gums and gently brush back and forth.
  • Chewing surface: Use the toothbrush as shown, and applying slight pressure, brush back and forth over the chewing surface.
  • Inside surface of the front teeth: Angle the brush as shown and use gentle back and forth strokes with the end of the brush.
  • Tongue: Brush the tongue in a back-to-front sweeping motion to remove food particles and freshen your mouth or you can use one of the many tongue scrapers available.


Flossing the teeth is a very important adjunct to tooth brushing for good oral hygiene. Studies have even demonstrated that those who floss regularly have a decrease in periodontal disease, bad breath, and cavity incidence. Unfortunately, many people do not floss, and so the increase in periodontal disease is seen. Flossing, as many people believe, is not used to remove food particles only. It is used to remove plaque under the gums, which is the invisible film of bacteria that constantly forms on teeth. Floss allows one to go in between the teeth, and scrape the surfaces clear of this plaque and bacteria.


A 12 to 18-inch piece of floss should be used first. By placing a few inches around the middle fingers on either hand and then using the thumbs for control, one places the floss in between teeth. Again, you can divide the mouth into sections. The important thing to remember is that you should get sufficient pressure to get in between the teeth. Pressure should be placed on either side of the teeth once the floss is an incorrect position. One must get under the gum line to loosen the debris, plaque, and bacteria. This area is called the sulcus. A good way to remember how long to stay in this area and clean is to count the up and down strokes on each tooth. Eight to ten strokes on each surface should be quite sufficient. The amount of time might seem excessive, but the rewards are great for your dental health.

Do questions arise on how often one should floss? The answer is that to be effective, one should floss each day. What kind of floss is best? There are many flosses to choose from on the market. Each one works. Personal preference is up to the patient. Thickness, waxed or unwaxed, etc. are for the difficult spaces that exist in teeth. Flavoured, non-flavoured flosses are available, again it is a personal preference of the patient. The main thing to remember is to floss on a regular basis to maintain good oral health. What if one finds it difficult using floss due to dexterity problems or a handicap? There are commercial devices that can aid one in overcoming these problems. Recently, a company has developed an electric motor type flossing device. more on flossing

Tongue scraping & bad breath

Ninety per cent of bad breath is caused by bacteria and dead cells on the back of the tongue. The best way to remove the odour is to remove build-up on the tongue. Tongue scrapers were developed to remove these dead cells and bacteria.

Things one can do to prevent bad breath:

  • Brushing and flossing regularly, including tongue surface, decrease bad breath.
  • Fibrous vegetables, such as celery sticks and carrots, aid in keeping the tongue surface clean.
  • Foods rich in proteins can cause bad breath. Dairy products, meats, fish etc., cause this by breaking down the bacteria on the tongue. The proteins, in turn, cause sulfur to form which causes bad breath.
  • Keep the mouth moist. Saliva flow keeps tongue surface clean.
  • If the odour is noticed. more from the nose, the respiratory infection may be the culprit. See your physician.

Following his 2009 graduation, he proceeded to join the AEGD residency program in Arizona, where he expanded his clinical knowledge and enhanced his ability to treat complex cases.

A Burlington native himself, Dr. Hamamy moved back in 2010 to support and promote healthy oral hygiene in his community, where he has been both nominated and awarded with the Reader’s Choice Award. He considers dentistry a privilege and takes pride in keeping up to date with the latest advancements in the industry.

Dr. Hamamy’s passion to reach out and give back extends past his immediate community. He spent 2008 in Fort Myers, Florida treating underprivileged children and families in need of dental care. When not attending to patients, Dr. Hamamy serves as a clinical instructor and advisory board member at the Canadian Academy of Dental Hygiene.
