Wearing braces is a common step toward achieving a straighter smile, yet many individuals undergoing orthodontic treatment experience temporary tooth sensitivity to cold. This sensation, from mild discomfort to a sharp twinge, is a frequent concern. This article will explain the reasons behind this heightened sensitivity, outline practical steps for managing it, and indicate when professional advice is needed.
How Braces Lead to Sensitivity
Braces function by applying continuous, gentle pressure to gradually shift teeth into new positions within the jawbone. This mechanical force initiates a biological response in the surrounding dental tissues, including the pulp and periodontal ligament. The pressure can cause micro-inflammation and changes in blood flow within the dental pulp, leading to discomfort. This process of tooth movement can irritate the supporting ligaments and nerves, contributing directly to temporary sensitivity.
The movement of teeth can also lead to the temporary exposure of dentinal tubules, which are microscopic channels within the dentin. When the protective outer layer of enamel thins or the gums recede, these tubules become exposed, allowing external stimuli like cold temperatures to reach the sensitive pulp. While braces do not directly cause gum recession, the movement of teeth can sometimes contribute to it, especially if there is pre-existing thin gum tissue or gum disease. Aggressive brushing techniques can also cause gums to recede, further exposing the sensitive root surfaces.
Coping with Sensitivity
Managing tooth sensitivity while wearing braces involves several practical home care strategies. Using a desensitizing toothpaste containing specific ingredients can help block pain signals from reaching the nerves within the teeth. Consistent use of these toothpastes over a few weeks typically yields noticeable improvement.
Employing a soft-bristled toothbrush with a gentle, circular brushing technique is also important to prevent further gum recession and enamel wear. Maintaining excellent oral hygiene is important, as plaque buildup and gum inflammation can exacerbate sensitivity. Rinsing with warm salt water can help soothe irritated gums and reduce discomfort.
Dietary adjustments can also alleviate sensitivity. Avoiding extremely hot or cold foods and beverages, such as ice cream or very hot coffee, can help prevent triggering sharp pain. During the initial days after braces are placed or adjusted, consuming soft foods like yogurt, mashed potatoes, or soup can significantly reduce discomfort by minimizing pressure on the sensitive teeth. For irritation caused by brackets or wires rubbing against the mouth, applying orthodontic wax can create a protective barrier.
When to Consult Your Orthodontist
While some degree of temporary tooth sensitivity is a normal part of orthodontic treatment, certain symptoms warrant a professional evaluation. If sensitivity is persistent, severe, or worsens despite home care measures, contact your orthodontist. Normal discomfort typically subsides within a few days to a week after adjustments.
You should also seek professional advice if the sensitivity is accompanied by other symptoms, such as swelling, fever, or significant pain when biting down on a specific tooth. These could indicate an underlying issue beyond typical orthodontic tooth movement, such as a cavity, gum inflammation, or even a cracked tooth. Concerns about loose or broken brackets or wires should also prompt a call to your orthodontist, as these issues can cause irritation and affect treatment progress.
