As the saying goes, "Toothache is not a disease, it hurts so much.". Once teeth hurt, it seems like the only real solution is to see a dentist. Of course, it is important to understand the true cause of tooth pain. There are many reasons that can cause this symptom, not just simple tooth decay. Today, let's take a look at the 11 common causes of toothache and their corresponding solutions. If you have toothache while eating ice cream or drinking cold water, it may be caused by sensitive teeth. This is because the patient's enamel has been worn thin or completely worn out; Grinding teeth, consuming acidic foods, acid reflux, or frequent vomiting can all cause thinning or wear of enamel. At the same time, the sensitivity of teeth to heat is usually caused by pulp or nerve problems, which is one of the final symptoms before nerve death. Teeth that are deeply corroded or have cracks can ultimately lead to nerve death, requiring root canal treatment. The treatment method for cold sensitivity of teeth depends on the degree of pain. Patients can use toothpaste containing potassium nitrate or tin fluoride (such as Comforte) to alleviate dull pain or mild sensitivity. If the sensitivity is high, a desensitizer can be used. More severe sensitivity requires the use of a dental crown to fully cover the remaining tooth structure. The cause of temporomandibular joint disorder is not always very obvious. It can be caused by injuries to the lower jaw, such as being hit, or by grinding teeth, arthritis, or dislocation of intervertebral discs between the skull and mandible. The treatment plan depends on the cause. If patients experience joint pain, headache, restricted mouth opening, and facial pain, injecting botulinum toxin into the chewing muscles can help alleviate the force they experience during contraction. Other more cost-effective therapies include the use of customized or over-the-counter dental protectors, physical therapy, taking nonsteroidal anti-inflammatory drugs (such as ibuprofen or naproxen) or muscle relaxants, or using heating pads. Brushing teeth too hard can cause gum recession. Applying too much force during brushing can actually cause toothache. This will wear down the actual tooth structure and cause gum recession that covers the root of the tooth. Patients will notice that they are extremely sensitive when eating cold food because the root structure of their teeth is exposed. Response plan: Stomatologists can place fillers of the same color as the teeth in the area where the patient's teeth are worn out, or perform gum regeneration surgery to restore the gums to their original height. To avoid excessive force, patients can also use high-quality electric toothbrushes or ultra soft bristled toothbrushes to brush their teeth. I have recently undergone teeth whitening. Teeth whitening involves placing chemical oxidizing bleach on the surface or inside of teeth, reacting chemically with them to whiten the color of the teeth themselves. This operation can cause tooth sensitivity, as bleach can cause temporary porosity in the teeth. This type of problem can generally self alleviate within a few days. The response plan is to use toothpaste containing potassium nitrate or tin fluoride, which can reduce tooth sensitivity when used for brushing. Gingival infection Many people suffer from periodontitis, which has a incidence rate of more than 50% in adults. Even without periodontitis, the gums can still be infected. When bacteria or pathogens enter the area of teeth (gums) and multiply
