A retainer is a customized orthodontic appliance, which can be removable or fixed, designed to hold teeth in their new positions after treatment. The device prevents teeth from shifting back, but the constant pressure it exerts can cause general discomfort. This aching is common, especially when a new retainer is first worn or after a period of not wearing it. The following steps provide solutions for managing this discomfort and addressing localized sore spots.
Immediate Relief for Pressure Discomfort
The generalized aching sensation is typically a reaction to the pressure applied by the retainer as teeth settle into alignment. Over-the-counter pain relievers can be an effective initial measure for this discomfort. Acetaminophen is preferred over anti-inflammatory options like ibuprofen, as anti-inflammatory drugs may interfere with the biological processes involved in tooth movement.
Applying cold therapy can help numb the area and reduce minor swelling. A cold compress or an ice pack wrapped in a cloth can be placed on the outside of the cheek for 10 to 20 minutes. Consuming cold foods, such as smoothies or yogurt, offers a similar soothing effect.
Modifying your diet can significantly improve comfort during the first few days when teeth feel tender. Stick to soft foods that require minimal chewing, such as mashed potatoes, soups, and soft pasta. Avoiding hard, crunchy, or sticky foods prevents additional pressure on sensitive teeth until your mouth fully adjusts, which typically occurs within a week.
Addressing Mechanical Irritation and Sore Spots
Localized pain, often described as a sharp or rubbing sensation, is caused by the retainer irritating soft tissues like the cheeks, gums, or tongue. This mechanical irritation is best managed by creating a barrier between the device and the sensitive tissue. Orthodontic wax is the standard solution, acting as a smooth shield over any rough or protruding edges.
Applying Orthodontic Wax
To apply the wax, wash your hands and dry the specific area on the retainer, as the wax adheres better to a dry surface. Break off a small, pea-sized piece and roll it between your fingers to warm and soften it. Gently press the malleable wax onto the sharp part of the retainer and flatten it to create a smooth, protective surface.
Salt-Water Rinses
If irritation has resulted in a mouth sore, a salt-water rinse can promote healing and provide temporary relief. Dissolving one teaspoon of salt in warm water creates a mild antiseptic solution that helps reduce inflammation and wash away bacteria. Rinsing several times a day can soothe the sore and speed up the healing process. Maintaining excellent oral hygiene, including cleaning the retainer as directed, also helps prevent bacteria buildup that could worsen irritation.
When to Consult Your Orthodontist
While some initial discomfort is expected, certain signs require professional attention rather than home remedies. If generalized pressure and aching persist with the same intensity for more than five to seven days, a professional check of the retainer’s fit may be necessary, as normal discomfort should lessen noticeably within a week.
A consultation is also warranted if the retainer is visibly damaged, such as being cracked, warped, or bent, since a misshapen appliance applies uneven pressure. If a sharp edge or wire causes localized pain that cannot be covered by orthodontic wax, the device needs adjustment. Contact your orthodontist immediately if the retainer feels drastically too tight or too loose after consistent wear, or if you experience sharp, unexpected pain.
