Why are my teeth shifting?
Our teeth are constantly making minor movements and overtime, can become visibly crooked or crowded. Patients who have undergone orthodontic treatment are encouraged to wear either a removable retainer when they sleep or have a permanent retainer placed to keep the teeth from moving back to their natural position. Other reasons that teeth may shift include extraction, jawbone growth, bruxism, gum disease, and even the use of a CPAP machine in patients with sleep apnea.
Extraction
If one tooth is extracted, the surrounding teeth may start to shift in an effort to fill the space left after the extraction. This is why it is important to replace a missing tooth with a dental prosthesis such as a dental implant or dental bridge.
Jaw Bone Changes
Jaw bone growth typically affects adolescent patients who are still growing. As the patient grows and develops, the jawbone will grow along with them. Additionally, as adult patients get older, the jaw tends to grow forward and become more narrow. Changes in the jaw may cause only minor shifts in the teeth and need no additional attention whereas some patients may experience more severe shifting and need to have their bite corrected.
Bruxism
Bruxism is essentially grinding your teeth. Many people grind or clench their teeth in their sleep which can lead to tooth wear and shifting. Your dentist can have a custom night guard fabricated to help buffer the stress your teeth endure while you sleep.
Gum Disease
Come disease can greatly affect the stability of the teeth. When the gums are infected, the tissue becomes weak, leading to bone loss and mobility in the teeth. Maintaining good oral hygiene and regular visits to your dentist will help resolve any gum disease and prevent it from coming back.
CPAP
CPAP stands for “continuous positive airway pressure” and is used in the treatment of sleep apnea to ensure a steady flow of oxygen during sleep. Sleep apnea is a condition in which the tissues at the back of the throat relax during sleep, restricting the flow of oxygen. Most CPAP machines cover only the nose but some also cover the patient’s mouth.
Your dentist can help address any negative side effects from your CPAP machine to keep your mouth healthy and prevent shifting teeth.
Shifting teeth is not always an immediate concern, depending on the cause, but it is important to visit your dentist as soon as you notice any changes to your bite to prevent further movement. Your dentist will help determine the reason your teeth are moving and can help determine what path of treatment would be appropriate. If it is determined that you need orthodontic intervention, they will be able to refer you to an orthodontist or they may even offer clear aligner therapy in office.
