Dentist’s Perspective: Everyday Dental Insights
After five years of intense dental training, looking at people’s teeth has become second nature. When I meet someone for the first time, I often notice their teeth while they speak. Trying not to make it obvious is a skill in itself – haha!
Whenever people know I am a dentist, they ask about tooth sensitivity, brushing techniques, and orthodontic treatments. These are vast topics, but let me share them concisely for you.
The Anatomy of a Tooth
- A tooth has multiple layers:
- Enamel: The white outer layer, rich in calcium phosphate, a rock-hard mineral.
- Dentin: Beneath enamel, containing microscopic dentinal tubules.
- Pulp: Under dentin, holding nerves, blood vessels, and connective tissue.
- Cementum: Connective tissue binding tooth roots to gums and jawbone.
- Periodontal ligaments: Fibers holding the tooth tightly against the jaw.
Isn’t it amazing how a tiny tooth holds such complexity?
Understanding Tooth Sensitivity
Tooth sensitivity is when enamel or cementum loss cause exposure to underlying tissues causing short, sharp pain arising from exposed dentin in response to stimuli typically thermal, evaporative, tactile, osmotic, or chemical.
Some of the etiological factors for enamel loss are using the wrong brushing technique or para-functional habits such as clenching of teeth. Cemental loss can be due to gum recession or diseases affecting the periodontal ligaments.
Tooth sensitivity varies from mild to severe. If the sensitivity/pain is mild and below are some tips to manage mild sensitivity.
- Use sensitivity toothpaste with a soft-bristled toothbrush.
- Practice correct brushing techniques (explained below).
- Include mouth rinses in your routine.
- Avoid acidic fruits and beverages.
If you have used all the above for over two weeks and the pain is still persistent, increasing, or unbearable, somehow hindering your daily life, visit your dentist for further evaluation and treatment.
Dental professionals have accepted different tooth-brushing techniques. No single brushing method suits everyone. Techniques vary based on dental needs.
Tooth-Brushing Techniques
- Modified Bass Technique
- Modified Stillman’s Technique
- Fones Method or Circular Scrub Method
- Charter’s Method
Modified Bass Technique is one of the tooth brushing techniques which can integrate into regular life as a routine oral hygiene measure.
It removes plaque (dirt accumulated on the teeth over the time). The technique consists of vibratory and circular movements with a sweeping motion. The toothbrush bristles are placed at 45 degrees to the gum.
Bristles vibrated by moving the toothbrush handle in a back-and-forth motion. Bristles are sweep over the teeth, away from the gum line in a single stroke. Three or two teeth brushed together at the same time.
Modified Stillman’s Technique can be recommended for cleaning the areas with progressing gum recession and root (part of the tooth below the gum line and helps hold the tooth into the jaw) exposure to prevent abrasive tissue destruction. Three or two teeth brushed together at the same time.
The toothbrush bristles are placed half on the gum line and half on the tooth surface. Then with short back-and-forth motions, the bristles are swept away from the gum line. Stroke should, however, not be harsh. Using a soft toothbrush will prevent damage to the surrounding tissues.
Charter’s Method is suitable for those wearing fixed partial dentures or orthodontic appliances, individuals with exposed tooth roots, and open interdental spaces. A soft/medium multi-tufted toothbrush is advisable.
Bristles are placed at 45 degrees onto the gum with bristles directed towards the occlusal surface (chewing surface of the teeth), with mild short circular strokes or small back-and-forth motions. This helps in removing debris from brackets and arch wire placed for orthodontic treatment.
Brushing Techniques for Kids
Fones Method or Circular Scrub Method can be used for young children, patients lacking dexterity, or physically disadvantaged individuals. The bristles are moved on the tooth surface in circular motions ensuring that teeth and gums are covered.
For teaching toddlers this brushing technique, kids can be asked to make big circles in the air, gradually reducing the diameter of a circle until the kid starts drawing a circle in front of the mouth. Now the child is ready to move to the tooth surface. Make sure the bristles cover the teeth and gums.
Always use gentle motions and a soft-bristled toothbrush. Replace your toothbrush every 3-4 months or sooner if bristles fray.
Orthodontic Treatment: Best Age
Growth is crucial for orthodontics. Treatment usually begins between 9-14 years. However, 12-13 years is ideal as about half of adolescent growth is complete, making tooth and jaw adjustments easier.
Regular dental check-ups are the best way to know if your child needs orthodontic care.
Final Recommendation
While these tips can guide you, consult your dentist for personalised advice. Waiting until problems worsen is unwise.
