There is nothing more annoying than a toothache. At first, it may start as sharp twinges in the tooth that come and go, but over time, the pain intensifies and can spread, causing discomfort in the head, ear, and even making activities like eating and sleeping difficult. Tooth pain when applying pressure is also common, heightening the discomfort with every contact.
Why Does Toothache Occur?
Toothache is one of the most common dental conditions and arises when the dental nerve is affected by cavities, infections, inflammation, or trauma. Inside the teeth, there are arteries, veins, and nerves that are sensitive to cold, heat, and pressure. When the dental enamel is damaged, the interior of the tooth is exposed, allowing bacteria to access the dental pulp and cause an infection or inflammation. Toothache is especially intense because the inflammation cannot expand, and the pressure is concentrated in a specific point. This phenomenon makes toothache so sharp and persistent.
Main Causes of Toothache
- Advanced Cavities: The most common cause is cavities, which progress in depth until they reach the nerve.
- Tooth Trauma: Blows can damage the enamel and expose the inner parts, making the molar vulnerable to infections.
- Bruxism: The habit of grinding teeth (bruxism) wears down molars and can cause pain and sensitivity.
- Emergence of Wisdom Teeth: The eruption of wisdom teeth is often painful, especially if there isn’t enough space in the mouth, causing swelling and even an abscess.
- Gum Diseases: Diseases such as gingivitis and periodontitis can spread to the roots of the molars and cause discomfort.
- Lack of Dental Hygiene: Poor hygiene is one of the frequent causes of cavities and the initial cause of many toothaches. If food debris and bacteria are not removed, the teeth can suffer damage and, over time, cause pain.
Common Symptoms
Toothache can manifest in different ways. Some people experience stabbing or throbbing pain in the tooth while chewing, while others feel a constant pain that worsens at night or when lying down. It is also possible to feel slight stabs in the tooth when consuming very cold or hot foods or drinks. If the pain is very intense or accompanied by a gum abscess, it is likely that the infection is advanced and requires immediate attention.
Professional Treatment for Toothache
In the case of a toothache, the most advisable course of action is to visit a dental clinic. A dentist can evaluate the cause and recommend the appropriate treatment to relieve the pain and address the underlying issue. Depending on the cause, the treatment may include:
- Deep Cleaning: If the pain is caused by a mild infection or plaque buildup on the gum, a deep cleaning can help eliminate bacteria and reduce the pain.
- Dental Fillings: In the case of a cavity, the dentist will clean the cavity and place a filling to protect the nerve and prevent future discomfort.
- Root Canal Treatment: When the infection has reached the nerve, a root canal treatment may be required. This procedure removes the infected pulp, thereby relieving the pain.
- Tooth Extraction: In extreme cases, such as the painful eruption of a wisdom tooth or a severely affected tooth, extraction may be necessary.
- Antibiotics and Anti-inflammatory Treatment: If the pain is accompanied by an abscess or swelling, the dentist may prescribe antibiotics or anti-inflammatory medication to control the infection before starting treatment.
How to Act if You Have an Abscess
A dental abscess or gumboil is a buildup of pus caused by an infection that can occur in the gums or at the root of the tooth. Abscesses are painful, and without treatment, the infection can spread to other areas. If you have an abscess, it is crucial to visit the dentist so they can treat it properly and prescribe the necessary treatment to avoid complications.
Frequently Asked Questions About Toothache
Why Do I Feel Sharp Pain in My Tooth?
Sharp or stabbing pain in a tooth often indicates that the dental enamel is damaged and the nerve is exposed to external stimuli, such as heat, cold, or pressure. It can also be a sign of an infection or inflammation in the dental pulp.
What Should I Do If I Have a Toothache That Won’t Improve?
If the toothache does not improve, even after avoiding contact with cold or hot foods, it is essential to visit a dental clinic. Dentists can perform an accurate evaluation and apply treatments that relieve pain safely and effectively.
Toothache Prevention
The best way to avoid toothache is to maintain proper oral hygiene and schedule regular visits to the dentist to monitor dental health. Some prevention tips include:
- Brushing your teeth after every meal and using dental floss to remove food particles.
- Reducing sugar consumption to prevent cavities.
- Using antibacterial mouthwash to keep gums healthy.
- Avoiding bruxism (teeth grinding or clenching) by using a mouthguard if necessary.
