A wiggling permanent tooth accompanied by pain is a serious sign that the tooth’s supporting structures have been compromised, representing a genuine dental emergency. Unlike a baby tooth, an adult tooth is designed to remain fixed, suspended within the jawbone by the periodontal ligament. Excessive movement signals a loss of attachment due to disease, injury, or infection. This situation requires immediate professional evaluation because the pain and mobility indicate active damage to the bone or soft tissue. Prompt intervention to stabilize the structure and address the underlying cause significantly increases the potential for saving the tooth.
Common Reasons Your Tooth Is Loose and Hurting
The most frequent non-traumatic cause of adult tooth mobility is advanced periodontal disease, often referred to as gum disease. This chronic bacterial infection causes inflammation that progressively destroys the alveolar bone and the specialized ligaments anchoring the tooth root. As the supporting bone structure diminishes, the tooth loses its stable foundation and begins to shift under normal biting pressure, which can cause pain.
Acute trauma, such as a blow to the face, is another common reason for sudden tooth movement and pain. A physical impact can damage the periodontal ligament fibers that hold the tooth in its socket, resulting in a condition called subluxation where the tooth is loose but not fully dislodged. Even if the tooth does not appear broken, the internal supporting tissues can be injured, and the pain is a direct result of this ligament damage and inflammation.
A dental abscess or severe infection near the root tip can also lead to painful tooth mobility. An abscess is a pocket of pus that forms when bacteria from deep decay or a crack invade the tooth’s pulp and spread to the bone at the root end. The buildup of pressure and the destruction of the surrounding bone by this infection can push the tooth slightly out of its socket or severely weaken its support, causing it to feel loose and throb with pain.
Immediate Steps to Take Before Seeing a Dentist
While waiting for your appointment, stabilize the tooth and manage discomfort without causing further injury. It is important to resist the urge to constantly touch, push, or wiggle the tooth, as any movement will further irritate the compromised supporting ligaments. You should immediately switch to a soft or liquid diet and strictly chew on the opposite side of your mouth to minimize force on the affected area.
For pain relief, over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are often recommended because they both reduce pain and help decrease inflammation and swelling. Acetaminophen is an alternative pain reliever if you cannot take NSAIDs due to stomach issues or other health concerns. Always follow the dosage instructions on the packaging and avoid placing any medication directly against the gum tissue, as aspirin can cause a painful chemical burn.
To soothe irritated tissues, gently rinse your mouth with a warm salt water solution several times a day. Mix about half a teaspoon of salt into eight ounces of warm water and swish it gently around the affected area for 30 seconds before spitting it out. If swelling is noticeable on the outside of your face or jaw, applying a cold compress to the cheek for 15 to 20 minutes at a time can help reduce the swelling.
How a Dentist Will Diagnose and Treat the Issue
The dentist will begin the diagnostic process with a thorough clinical examination, including a precise assessment of the tooth’s mobility. Using two instruments, the clinician checks the tooth’s movement horizontally and vertically to assign a mobility grade, such as Grade 1 (slight movement) or Grade 3 (severe movement with vertical displacement). A periodontal probe measures the depth of the gum pockets around the tooth, helping determine the extent of ligament and bone loss caused by gum disease.
Diagnostic X-rays, typically periapical views, are taken to visualize the underlying bone structure, which is not visible during an oral examination. These images reveal the remaining alveolar bone support, the presence of root fractures, or a dark shadow indicating a dental abscess at the root tip. The treatment path is determined by the findings of this examination and radiographic analysis.
If trauma is the cause, the immediate treatment often involves temporary dental splinting, where the mobile tooth is bonded to the adjacent stable teeth using a composite resin and sometimes a thin wire. This stabilization acts like a cast, immobilizing the tooth for several weeks to allow the damaged periodontal ligament to heal and reattach to the root.
For mobility caused by periodontal disease, the procedure is scaling and root planing, also known as deep cleaning. This non-surgical treatment uses specialized instruments to meticulously remove hardened plaque and calculus from above and below the gum line down to the periodontal pocket. The goal is to smooth the root surfaces, eliminating bacteria and toxins so the gums can tighten and reattach to the tooth.
If a severe abscess is present, a root canal procedure is often recommended to save the tooth. This involves removing the infected pulp, then cleaning and sealing the inner root canals. However, if the tooth is non-restorable due to a severe, irreparable fracture, extensive decay, or catastrophic bone loss (Grade 3 mobility), extraction may be the only viable option to prevent the spread of infection.
