WHY ARE MY TEETH SENSITIVE TO HOT AND COLD?
If you’ve felt a short, sharp twinge of pain when you take a sip of a cold drink, eat an ice cream or a bowl of soup, or even when you breathe in cold air on a winter’s day, then it could be a sign that you have tooth sensitivity.
Your teeth become sensitive to cold and hot when the softer, inner part of the tooth called ‘dentine’ becomes exposed. This can happen if you have gum disease, as this can lead to receding gums, or if enamel wears away. Dentine is full of tiny channels that run towards the nerve at the centre of the tooth. This is why, when you eat or drink something cold or hot, it can stimulate the nerve inside and cause that nasty twinge of pain.¹
WHY ARE MY TEETH SENSITIVE TO SUGAR?
Cold and hot foods aren’t the only triggers that can cause sensitivity pain. Your teeth can be sensitive to sweets and other sugary foods, as well as sour food and drinks and you may experience that familiar short, sharp pain when you eat sweet or sour flavours. This is due to the same reason that your teeth are sensitive to temperature changes, they can stimulate the nerve inside the tooth.
There are other reasons your teeth may be sensitive to cold, hot, sweet or sour foods:
- If you have a cracked tooth, this can also affect the nerve deep inside the tooth and make you sensitive to the things you eat and drink, causing pain.²
- Your teeth may be sensitive to heat and cold after a new filling.
- You may experience tooth sensitivity after tooth whitening treatments.
If your teeth hurt when you eat and drink something cold, hot, sweet or sour, then you should visit your dentist to identify the cause of your pain.
