Do hot or cold foods cause a sharp twinge of pain in your teeth? Sensitive teeth are usually a symptom of an underlying dental problem. It can be caused by enamel erosion (wear and tear) and gum recession exposing the roots of the tooth. It can also be a side effect of teeth whitening treatments or after dental procedures like fillings or a 韓国ホワイトニング cracked tooth.
1. Fluoride 韓国ホワイトニング
Fluoride is a mineral that strengthens teeth, making them more decay resistant. It is often found in toothpaste and mouthwashes. It is also added to community water supplies as a public health measure to reduce cavities.
Teeth sensitivity can be caused by many things, including the wearing down of tooth enamel (which is more common as we age), gum disease or a cracked tooth. It can also be caused by certain foods and drinks, such as extremely hot or cold food and drink or acidic ones.
Tooth sensitivity can be treated by using a desensitizing toothpaste. This contains ingredients that help to block the nerves in the tooth, reducing the feeling of pain. It may take a few applications to feel the effect. In more severe cases, a dentist can apply a bonding resin to the exposed root surfaces of the tooth or perform a surgical gum graft. This involves taking a small piece of gum tissue from elsewhere in the mouth and attaching it to the sensitive area. This will protect the roots and stop them from exposing.
2. Mouthwash 韓国ホワイトニング
Many over-the-counter mouthwashes contain acids that can worsen teeth sensitivity in people with exposed dentin. This symptom occurs when the outer layers of enamel and cementum wear down, leaving the microscopic tubules (little canals) inside the dentin exposed to hot, cold, sugary or acidic foods. This can also be caused by gum disease, teeth grinding and whitening products.
If you are suffering from this condition, your dentist can offer you a range of treatments to reduce the symptoms and prevent further damage. They can advise you on how to improve your oral hygiene routine by recommending a fluoride toothpaste and using it as recommended, brushing your teeth last thing at night, with small circular movements and changing your toothbrush every two to three months, especially when it is worn. They can also recommend a desensitizing toothpaste that contains compounds that help block the transmission of sensation from the tooth surface to the nerve. You may need to try several brands before you find one that works for you.
3. Sealants
Sealants are plastic coatings that are painted on the chewing surfaces of back teeth (premolars and molars). They act like raincoats for your tooth enamel, protecting it from food particles and bacteria that can cause tooth decay.
Before applying the sealant, we will brush and floss to make sure your teeth are clean and ready. We will then paint the liquid sealant material onto the chewing surface of your tooth and shine a curing light to harden it. We may repeat this step to ensure the tooth is fully sealed. After the sealant is dry, we will floss between your teeth to make sure nothing got trapped, and check your bite to see if you have any gaps.
We recommend that children get sealants on their permanent molars and premolars as soon as those teeth come in, or no later than their sixth birthday. It is more cost-effective to apply sealants before the grooves of molars develop, and it is easier to clean teeth that have not yet grown cavities. Adults at high risk for decay can also benefit from sealants, especially those with deep molar grooves.
4. Dental bonding
Teeth bonding is a popular cosmetic dentistry treatment for repairing small cracks and chips, closing gaps, and improving the appearance of teeth. It is a painless minimally invasive procedure that doesn’t require anesthesia in most cases.
First, the dentist selects a composite resin color that closely matches the shade of natural tooth enamel. Then the dentist roughens and conditions the surface of the existing tooth to prepare it for bonding. Finally, the dentist applies the resin to the tooth and hardens it under a curing light.
The result is a smooth, polished tooth that looks like a natural part of your smile. Dental bonding can last up to ten years with good oral hygiene and regular dental checkups. However, if you grind or clench your teeth or chew on hard objects, dental bonding can chip and break. It is also not as strong as natural tooth enamel and may require a root canal if it becomes cracked or damaged. Dental crowns are a better option for major repair work or to replace a decayed tooth that has already undergone a root canal treatment.
5. Extractions
If the causes of teeth sensitivity are not addressed then it can lead to real pain. Sensitive teeth are a warning sign that something is wrong and the best course of action is to see a dentist as soon as possible to investigate the cause.
The sensitivity may be caused by tooth decay, worn enamel, cracked teeth or gum disease. Teeth can also become sensitive from drinking hot or cold foods and from brushing too hard. Some patients have sensitivity as a side effect from bleaching their teeth.
Other factors can lead to sensitive teeth such as a loss of the cementum that covers the root surface (dentine). This exposes the dentine and makes the tooth susceptible to painful stimuli.
Extraction is sometimes necessary if other treatments do not provide relief. However, it is important that the patient understands what is involved in an extraction procedure and the possible complications. Liaising with the patient’s medical team is also advisable prior to treatment.
