Yes you can!
VA Mare Island clinic provides necessary dental care for veterans who were not provided dental examination and treatment within 180 days of discharge and apply within 180 days of separation from the service. The time limit does not apply to veterans with dental disabilities resulting from combat wounds or service injuries. If a Veteran is 100% service connected, the Veteran can receive dental care from the VA.
If you are enrolled in the VA for healthcare, you may be eligible to apply for dental coverage through the VA Dental Insurance Program. This is a 3 year pilot project offering dental coverage plans through Delta Dental and Metlife. To apply, visit VA benefits webpage
