Dr. Du persuaded me to have my 4 upper front teeth covered by
whiter crowns for cosmetic reason. The crowns she installed
cut into my lower lip, causing constant pain. She offered to
redo the crown at reduced price, but the new crowns did not
reduce the pain on the lower lip. I then paid her in full to redo
the crowns a third time. The problem persists. Now I need to
wear upper teeth guard to prevent my upper teeth from hurting
my lower lip. Another right side molar crown that Dr. Du
installed caused TMJ pain that she could not fix. Another
dentist adjusted it for me and was able to remove the TMJ.
