About Dr. Kathy L. Marshall, DDS
Dr. Kathy L. Marshall, DDS, handles crooked smiles and underbites in Prince George’s County. Orthodontics reshapes bites in adolescence and adulthood alike, using wires, brackets, or clear aligners. No referral is needed; just walk in or give a call to set the first stage.
At 9470 Annapolis Rd in Lanham, the practice sits near the Capital Beltway’s Lanham exit, convenient from Bowie and Upper Marlboro. Drive south on Annapolis Road, and the office appears on the right just past the shopping plaza anchored by a hardware store. Park in the main lot and head straight inside.
Straightening solutions include traditional metal braces for teens and adults, ceramic brackets that blend with teeth color, and lingual braces mounted behind the teeth. For discreet corrections, Invisalign aligners slide over teeth and can be removed for meals and brushing. Retainers follow active treatment to lock in the new arrangement. Check the website whenever you need to verify insurance or ask about payment plans.
To arrange a visit or line up a consultation, call (301) 731-4522 during business hours. From the office, exit onto Annapolis Road heading west—two traffic lights bring you to the driveway. The directions are easier to follow on the map here. Folks say it’s the fastest route once rush hour fades.
