I was just going to say that tea tree essential oil used straight could be causing inflammation and pain, if that’s the type she’s using. It’s extremely strong stuff. I would recommend melting a cup of coconut oil and mixing only 2-4 drops of tea tree essential oil into it. Then store the infused oil and use it for oil-pulling daily for a while. The coconut oil has the added bonus of being anti-inflammatory as well as antifungal. I oil-pull almost every day and my non-candida-related dental issues have improved dramatically (I never had thrush to begin with).
