No need for the card to claim free dental treatment. They cannot demand it. If you feel super conscientious you can give them the details once it arrives. Your GP or midwife can provide and sign the form. I've always got them back pretty quick, within a couple of weeks I think.
I sent mine off a week ago and haven't received it yet. you do need to fill a form out and get the midwife to sign it though. I just asked at my docs and they got the midwife to sign it next time she was in and sent it off. I had to pick a prescription up at the same time, I ticked that I had an exemption card and they just signed something saying that they hadn't seen it. I need to go to the dentist and still don't have my card so I will be doing the same, I need route canal so its not like i'm trying to get out of a few £ its about £50
your midwife will give you a form at your booking appointment and the card comes through about a week or so later. If you let your dentist know they will make a note of it and you might need to show them when you go back but they should be fine!
I'm 33 weeks and only sent mine off 2 weeks ago ish even though I should have done it after my booking appointment at 8 weeks but it kept slipping my mind. Anyway I recieved it this morning. I read online you should receive it within 10 days of them receiving your application.
Call your midwife and/or GP to get a form and get it sent off. It will be backdated but you MUST get one. The NHS Business Services Authority have been issuing fines to people claiming exemption without having registered for the card. The box you are asked to tick doesn't say 'are you pregnant and entitled to free care?' it says 'has a valid maternity certificate'. They do not care if you are entitled to it anyway, without the card you are fraudulently claiming something free.
