Experimental: Botulinum Toxin type A
Participants will be injected intramuscularly with total of 50 Units, 25 units of Botulinum A per temporalis muscle. The BTX injection will be prepared by dissolving 100 U vial in 2 ml of 0.9 % of Sodium Chloride (NaCl), yielding 25 U/ml. Each participant will receive 0.1 ml of BTX/NaCl mixture in 5 spots per temporalis muscle.
Drug: Botulinum Toxin type A
All the participants meeting the inclusion criteria will be seen for a total of 4 visits and 3 phone interviews. Participants will complete a set of self-reporting questionnaires, assessing the disability associated with Headaches Attributed to TMD, and other pain-related TMD diagnoses, the impact of headaches on the quality of life, and psychosocial distress questionnaires.
In addition, they will undergo 3 cycles of treatment, each 12 weeks apart.

- Reduction in number of Headaches Attributed to TMD (HA) [ Time Frame: Every 12 weeks up to 1 year ]Self-report
- Reduction in Headache Impact Test-6 score (HIT-6) [ Time Frame: Every 12 weeks up to 1 year ]Self-report.
- Pressure Pain Threshold [ Time Frame: Every 12 weeks up to 1 year ]Using algometer at the temporalis and masseter muscles
- Graded Chronic Pain Scale (GCPS), 1 and 6 months score [ Time Frame: Every 12 weeks up to 1 year ]
This scale provides the characterization of chronic pain as well as disability associated to the chronic pain. This scale includes 3 items for pain intensity and 4 items for function, one item for number of days of pain.
Characteristic Pain Intensity (CPI): compute mean of items 2-4(pain right now, worst pain, average pain), and multiply by 10.
Interference Score: compute mean of items 6-8 (daily activities, social activities, work activities), and multiply by 10.
Interpretation Determination of Chronic Pain Grade Grade 0: (no pain, no disability)
I Low intensity pain, without disability: (Less than 50 points in CPI and less than 3 point in disability)
II: High Intensity pain, without disability: (Greater than or equal to 50 points in CPI and less than 3 point in disability
III: Moderately limiting: N/A in CPI and 3-4 points in disability
IV: Severely limiting: N/A in CPI and 5-6 points in disability
- Jaw Functional Limitation Scale [ Time Frame: Every 12 weeks up to 1 year ]Comprised within a 20-item instrument. a single global score of "jaw functional limitation" can be computed as the mean of the available items. Sub-scale scores for each type of functional limitation are computed, as follows: Mastication: mean of items 1-6. Mobility: mean of items 7-10. Verbal and non-verbal communication: mean of items 13-20. Norms have not yet been established for this instrument.
- Migraine Disability Assessment/ HA-TMD [ Time Frame: Every 12 weeks up to 1 year ]
This self reported instruments comprise 6 items and based on the number of days of disability a MIDAS level is calculated as follows:
0 to 5- MIDAS Grade I, Little or no disability 6 to 10- MIDAS Grade II, Mild disability 11 to 20- MIDAS Grade III, Moderate disability 21+ MIDAS Grade IV, Severe disability
