Hi CM3171, and thanks for your post and question, it is a good one!
I am hopeful others in the community will see your inquiry and respond by sharing their own anecdotal experiences using this medication (Breztri).
You may be aware, dental issues have been reported as a side effect for some folks who use it Breztri.
As a reference, here is a link to information regarding its use. I know it is lengthy but, there is a section highlighted (entitled 'side effects'😉, which addresses your concern. I do hope you find this to be helpful in a practical way.
