When inhaling cold air through your teeth sets off a stabbing nerve pain, you know something is wrong.
For anyone with sensitive teeth, milkshakes, ice cream and just about anything cold can become a painful ordeal.
As annoying as this reaction may be, it serves a purpose, says German dentist Dr Jochen Schmidt.
“It’s a protective reflex of the tooth to prevent sudden temperature changes causing enamel cracks or nerve damage.”
There are many causes of sensitive teeth, and one common reason is receding gums, which often occurs with age.
Where the gum recedes, the so-called neck of the tooth is exposed, making it easier for temperature changes to reach the tooth nerve, which then triggers a reaction.
But there are other possible causes, notably, thinning enamel, cavities, leaky fillings, poorly-fitting crowns and an inflammation of the periodontal tissue.
Dr Schmidt says that these issues can manifest as sensitivity to cold.
If in doubt, it’s always best to consult a dentist.
Four tips for dealing with sensitive teeth:
It can help to get used to eating ice-cold food and drinks in smaller bites or sips.
This helps your teeth better cope with the icy temperatures.
Toothpastes for sensitive teeth contain specific salts that can reduce the sensitivity of exposed tooth roots.
Dental practices offer various treatments for sensitive teeth, such as sealing the teeth with special varnishes.
Brushing your teeth too hard can wear away valuable tooth enamel over time and push back the gums.
An electric toothbrush with a pressure sensor that signals when you’re pressing too hard can be a helpful tool. – dpa
