Q. I\’m struggling with invisalign the thing is i have 2 very stubborn front teeth that have twisted inwards. i\’ve had invisalign for a few months now and i\’m nearing the treatment and those 2 teeth still haven\’t moved. what happens when i finish and the teeth are still like that? is there anything else i can do within my treatment time?,

Q. I am new to Invisalign now and have 17 upper trays, but this is combined with metal braces on my lower teeth. Wish they could have both been invisalign : ( Anyhow can you tell me what a good cleaning routine should involve? I understand you have to clean your teeth and aligners after each eating? What about every morning and night?,

Q. Hello doctor. I have heard that when you first get your aligners it can be quite painful. Can you tell me if it will be too painful for me to clean my teeth and floss? I don\’t want to let things slip you see. Cheers.,

Q. I\’d like to know if it\’s possible to very slightly increase the gap between my extremely tight fitting crowns, without having to take them out? I find it very difficult to floss, and have tried various techniques/floss. My hygienist & dentist both recommend Superfloss. However, this too is very difficult to use. Before my accident, my teeth had a usable gap between them. Now with the crowns, it\’s really difficult - to the point where I don\’t bother most days. All of my other natural teeth are fine, with a nice small gap and are easily flossed. I\’m wondering if there\’s some sort of very thin, fine gauge product akin to \’sandpaper\’, that could be used to very carefully just increase the gap by a few thousandths of a mil - just enough to make it possible to comfortably get the floss between my crowns? My dentist keeps saying just push it through and let it snap in to place. But this usually makes my gums bleed – hence my reluctance. I’m sure that if the crowns weren’t so tight that I’d be able to floss more easily, and therefore more regularly.,

Q. Ever since having the aligners etc i\’ve experienced very tender gums which now bleed every time i brush my teeth! I have ulcers on my tongue and very bad breath and i have no idea why, it\’s been since i started invisalign! What can I do to stop all of this? I\’m contemplating just getting rid of invisalign..,

Q. I\’m new to invisalign and haven\’t really asked my orthodontist any questions. I\’m a bit scared to brush my teeth, my friend had invisalign and said every time she brushed her teeth her gums bled and i don\’t want that to happen to me, she also said that it\’s very painful when flossing, so i\’m scared to floss too. I don\’t want my teeth decaying etc so what do you advise?,
