If you experience a sharp, fleeting pain when consuming hot coffee, cold water, or sweet treats, you're dealing with tooth sensitivity, also known as dentine hypersensitivity. This common issue occurs when the protective layers of your teeth wear down, exposing the underlying nerve pathways.
To understand sensitivity, you must understand the anatomy of a tooth:
When enamel or cementum is lost, these dentinal tubules become exposed. Hot, cold, or acidic stimuli travel through these open tubules and reach the nerve, causing that characteristic jolt of pain.
The primary culprits behind dentin exposure and sensitivity often stem from daily habits or underlying dental conditions:
Enamel, though hard, can be worn away by:
Receding gums are a major cause of sensitivity because the tooth root, protected only by the softer cementum, is exposed. Gum recession is often caused by:
Cracked teeth, chipped fillings, or areas of decay can also create openings that expose the sensitive dentin and lead to immediate, sharp sensitivity.
At TAG Dental in Johor Bahru, addressing sensitivity begins with correctly diagnosing the underlying cause. Our treatment options range from simple in-office procedures to restorative dentistry:
For mild to moderate sensitivity, professional-strength desensitizing agents or fluoride varnishes are highly effective. These materials work in two ways:
When sensitivity is caused by receding gums exposing the root, or by minor tooth structure loss (like a chip or erosion near the gumline), dental bonding is often the ideal solution.
If gum recession is severe, exposing a large portion of the root, a gum graft may be recommended. This surgical procedure involves transplanting a small amount of tissue to cover the exposed root, effectively restoring the natural protection and treating the primary cause of the sensitivity. Addressing underlying periodontal disease is also paramount.
For severe sensitivity caused by extensive enamel wear, deep cracks, or when sensitivity is persistent and chronic, a full dental crown may be necessary to completely cover and protect the tooth. If the sensitivity indicates pulp damage, root canal therapy might be the final step to eliminate the pain permanently by removing the inflamed nerve tissue.
The best defense against sensitive teeth is prevention, which requires a commitment to healthier daily oral care habits.
If you clench or grind your teeth, your dentist at TAG Dental can custom-fit you with a night guard. Wearing this appliance while you sleep protects your enamel from damaging forces, preventing further wear and sensitivity.
1. How long does sensitivity last after a dental filling? It is normal to experience temporary sensitivity for a few days to a few weeks after a new filling, as the tooth heals. If it persists beyond a month, consult your dentist.
2. Does whitening toothpaste cause sensitivity? Many whitening toothpastes contain abrasive or chemical agents that can contribute to sensitivity, especially if you have existing enamel erosion or gum recession.
3. Is sensitivity a sign of a cavity? It can be. Sensitivity is a common symptom of a cavity, particularly when the decay has reached the dentin layer. A dental examination is required to confirm the cause.
4. Should I switch to a new toothpaste immediately if I have sensitivity? You can switch to a desensitizing toothpaste immediately. However, it takes at least two to three weeks of consistent use for the blocking agents to provide maximum relief.
5. How often should I brush to reduce sensitivity? You should brush three times daily using a soft-bristled brush and a gentle technique to minimize plaque buildup without damaging the enamel or gums.
6. Can gum disease cause my teeth to feel sensitive? Yes. Gum disease causes gum recession, exposing the sensitive root surface. Treating the underlying gum disease is necessary to control the sensitivity.
7. Is it safe to use over-the-counter desensitizing gels? It is safest to consult your dentist first. They can recommend professional-grade agents or determine if an underlying problem (like a crack or cavity) needs attention before relying solely on a gel.
8. What is the difference between cold sensitivity and spontaneous tooth pain? Cold sensitivity is a sharp, brief pain that only occurs when exposed to cold stimuli. Spontaneous, throbbing pain that occurs without any stimulus is often a sign of a more serious issue requiring root canal treatment.
9. Can orthodontic treatment cause sensitivity? Temporary sensitivity is common immediately after braces or aligners are adjusted, due to the pressure on the tooth. This usually subsides within a day or two.
10. When should I see a dentist for sensitive teeth? You should book an appointment with TAG Dental if the sensitivity is new, severe, persistent, or is accompanied by other symptoms like spontaneous pain or swelling.
