Dr. Wall used Invisilign to correct my cross-bite, which caused me some trouble... It worked with little pain, time, or trouble and cost less than full braces. However, he was out of network & pricey for my other dental care. He can answer all your questions on TMJ and has a scientific mind like a steel trap. He seems very affable & intelligent. He's a thinker! His rooms/office do not seem fancy, but it is in a central location in Washington. He also was highly recommended to me by doctors in two other states.
