Dental health has impacts on whole body health. Finances should not be a barrier to good oral health and hygeine.
Finding a good dentist who accepts Denti-Cal can be difficult. Ask around, and don’t settle for the first dentist that comes up when you do a Google Search.
Places like MEND (Meet Each Need with Dignity) provides services to lo income people who do not have dental insurance. I believe USC and UCLA also have programs for this.
Don’t be ashamed. Poverty can be temporary, your smile is permanent.
