I had two crowns done by Dr. Mak and they both broke within two years. I went to another dentist who told me that these types of crown are not popular and hardly done anymore. I can see why. I had to fight with insurance and pay a very expensive out of pocket bill because insurance wont cover crowns that break in under 5 years. I am NOT a satisfied customer and do NOT recommend anyone who needs sturdy long lasting dental work to go here.
