A 59-year-old male asked:

can the extraction of an upper back molar tooth without bone grafting that resulted in a sinus droop commonly lead to a tmj disorder?

Not really: Keeping your mouth open wide for a period of time or stretching your jaw open wide might be a trigger and the last straw in developing some tmjoint symptoms, but it would only be temporary and short lived unless you already had other predisposing factors.
Dr. James Wright
Dentistry 33 years experience
Not directly : How long ago was the extraction? As it would take time for a sinus to droop. Which molar was extracted 1st, 2nd or 3rd. Typically the extraction would not lead to tmj, unless now the other teeth are making a premature contact on your lower teeth. If it was a recent extraction ; you had your mouth propped open, TMJ could temporarily ensue which usually goes away. If not, see a dawson or pankey dds.
Dr. Sam Markzar

No.. it can not: ....The procedure can not cause TMJ ... But you could have a temporary discomfort or joint inflammation/disk derranegement because of keeping your mouth wide open, ...Maybe for too long... But that it not related to actual extractioon procedure
Dr. Thjomas Heap
Cosmetic Dentistry 46 years experience
No: No unless the patient's jaw was opened too wide during the proceedure causing trauma to the tmj.
Dr. Michael Lebowitz
Dentistry 33 years experience
Extraction: The extraction and sinus will not lead to tmj/tmd symptoms directly. Indirectly the opening during surgery and the change in occlusion as a result of the missing tooth can lead to symptoms of the tmj.
Dr. Gary Kitzis
Prosthodontics 35 years experience
Extractions and TMJ: Not the extraction per se, but your having to open widely to get surgical access to the area can cause muscle or TMJ tenderness for a period immediately after the surgery but it would not likely cause a TMJ disorder to develop at a later time.
Dr. Ron E. Bell
Cosmetic Dentistry 45 years experience
Not normally: The extraction is the only item in your question which could lead to a TMJ issue, one with the trauma from the extraction or two the loss of the tooth losing posterior support of the mandible. There are sometimes referred pains from the sinus to the tmj.
Dr. Louis Gallia
Oral and Maxillofacial Surgery 45 years experience
Unlikely: Unlikely. Loss of posterior dental support can in some cases contribute to TMJ

Does a lower back ache mean I am in labor?

Dr. Jerome Yaklic

No: It could especially if it is crampy and comes and goes every few minutes. However, it could be due to additional strain in your low back muscles due to your expanding belly and less postural support from your stomach (rectus) muscles. It could also be pain in your pelvis (si joints) from the hip bones "moving" to create more room for your baby to come out. If uncertain see your healthcare provider.

Possible: Back pain in pregnancy is extremely common. The added weight and the change in the curve of the spine both contribute to the back pain.

Sometimes: Some stomach viruses can cause mouth ulcers. For example, herpangina and hand, foot and mouth illnesses are two common viral infections. They are annoying, but rarely dangerous. There are several other causes of mouth ulcers, including canker sores, minor trauma, or different viruses. In either case, the only treatments required are pain control and fluids.
