I had my teeth whitened last year by my dentist (trays made and bleaching gel) and I am supposed to do it every 6 months at home to keep up with it. I am due to do it about now but not sure wether its safe as I am pregnant? Does anyone know if it will be safe? I would ask my own dentist but not due check-up til July so any one who knows would be helping me alot 
Thank You :)
