Definitely recommendedPosted on Diego ArredondoTrustindex verifies that the original source of the review is Google. Tuve cirugía láser de un grande mucocele que tenía en mi labio y se solucionó mi problema muy bien, me explicaron el proceso con detalle, todo lo hicieron con mucho detalle y después me dieron seguimiento. Gracias!Posted on Jobelle MedinaTrustindex verifies that the original source of the review is Google. I recently underwent a soft tissue grafting procedure at Cosmodental due to receding gums, and I’m genuinely impressed with how smoothly everything went. Before the procedure, Dr. Segui explained everything thoroughly and made sure I understood what to expect, including clear post-care instructions. As someone who’s very anxious and scared of injections, I was extremely tense at the start, but Dr. Segui’s calm presence and gentle approach really made a difference. She checked on me constantly to ensure I wasn’t feeling any pain or discomfort. The entire procedure took about an hour, and I received post-surgical care right away. I expected several days of swelling, but surprisingly, I barely had any. After just two weeks, my gums looked healthy, and I healed much faster than I anticipated. Overall, I’m absolutely pleased with the experience and results. Highly recommended!Posted on Mary Rose LaurenteTrustindex verifies that the original source of the review is Google.

KNOW MORE ABOUT TMJD Treatment:

Oral orthotics, mandibular repositioning splints snore guards, oral sleep appliances and other customized oral appliances can be particularly effective for treating TMJ disorders, Bruxism, sleep apnea, snoring, and more.
There are two types of oral appliance therapy:
1. Customized oral appliances to align your jaw for the treatment of TMJ Disorders
2. FDA approved oral sleep appliances for the treatment of snoring and Sleep apnea.
TMJ appliances are customized to your specific jaw condition. Your jaw position not only affects the alignment in your TMJ, but also the position of your bite, head, neck, airway, and tongue position. Our doctor makes them small and comfortable so that you can talk in them as they often need to be worn during the day and night.
These appliances are very different from nightguards which are only meant to cover your teeth to reduce wear. Studies and experience have shown that nightguards used improperly can actually worsen a TMJ disorder.
Oral appliance therapy is a safe and successful treatment method for snoring and obstructive sleep apnea. Oral appliance therapy usually involves custom-fit oral sleep appliances that can improve your sleep and help manage your condition.
Oral sleep appliances fit like a sports mouth guard or orthodontic retainer and support your jaw in a forward position to assist you in maintaining an open airway.
Our trained doctor conducts a complete clinical evaluation including an examination of your jaw, teeth, tongue, airway, and any necessary testing, such as imaging of the jaw. Imaging is typically a Cone Beam CT or Diagnostic Radiographs. This lets our doctor visualize the anatomical problems in the jaw.
At Cosmo Dental, our doctor creates a personalized treatment plan for you and customizes your oral appliance using physical impressions of your teeth. These models are sent to a dental lab where your appliance is created by a qualified technician.
Once your oral appliance is ready, you return to the office for a fitting and our doctor adjusts your appliance accordingly to maximize comfort and effectiveness. You will also be provided with valuable information about how to clean and maintain your oral appliance.
Follow-up visits are necessary to ensure the optimal fit and success of your oral appliance. Our doctor might need to continue to adjust your oral appliance over time for the best results.
Cosmo Dental provides oral appliance therapy due to the many benefits, such as:
Whether you’re grinding your teeth, or your jaw is locking, or dealing with sleep apnea, oral appliance therapy can be a successful solution.
Our trained doctor also provides other treatments used in addition to oral appliance therapy, such as injections, Botox, Physical Medicine, Minimally Invasive surgery, medications, and lifestyle changes.
During your personal consultation, our doctor can discuss oral appliance therapy in detail, answer your questions, and help you determine if it’s right for you.

Facial pain can vary depending on the person. You might experience a full and throbbing feeling or an intense, stabbing pain or even burning.
You might experience facial pain due to changes in nerve signaling to the brain. These nerves can become extremely sensitive and the signals going to the brain might not switch off properly.
Pain that starts in the face could be the result of a nerve problem, an infection, or an injury.
Other causes of facial pain include:
Facial pain can also begin in the neck and radiate through the jaw and face.
Myofascial pain
Myofascial pain happens when the nerves connected to your muscles become irritated and small nodules form. This causes your muscles to become painful and bunch-up in areas called trigger points.
Myofascial pain in the jaw muscles can be associated with other symptoms, such as dizziness, eye twitching, ringing in the ears, and tearing. Tension headaches in the temples are typically the result of myofascial pain within the temporalis muscle (the jaw-closing muscle).
Trigeminal neuralgia
Trigeminal neuralgia involves sudden attacks of pain on one side of the face. The pain comes and goes suddenly. Some people might be free from pain for many months or years while others experience more frequent flares. This pain can be very severe and debilitating.
Trigeminal neuralgia is more common with aging and in women, and it’s often caused by impingement in the nerve by blood vessels.
Atypical trigeminal neuralgia and chronic regional pain syndromes
These refer to continuous pain that is aching to throb or burning. There can also be a sense of numbness or redness associated with them. They can be a result of some type of nerve injury.
If your facial pain is persistent and getting in the way of eating, talking, and daily life, you should visit Cosmo Dental for an evaluation and treatment. Our trained doctors work diligently to get to the root cause of your facial pain and provide the most appropriate solutions.
Our skilled doctors devise a personalized treatment plan to treat the underlying cause of your pain, give you relief, and protect your oral and musculoskeletal health.

If your TMJ disorder has caused problems with how your teeth fit together you may need treatment such as bite adjustment (equilibration), orthodontics with or without jaw reconstruction, or restorative dental work. Surgical options, such as arthroscopy and open joint repair restructuring, are sometimes needed, but are reserved for severe cases. Our doctor’s do not consider TMJ surgery unless the jaw can’t open, is dislocated and non-reducible, has severe degeneration, or the patient has undergone appliance treatment unsuccessfully.
