So as a new mum I get free dental care for a year. I'm really scared of dentists and hence haven't been for years and years. I have a mouth full of rotted and broken teeth

So I think I'm looking at implants, crowns, veneers etc to get my mouth looking shipshape. Will literally everything be free? I suspect it won't. What's considered cosmetic? On the left side, I have three teeth then nothing until one lonely tooth halfway back which is half rotted.
I'm scared, but figure if I can grow a baby then I can do this! My HV recommended a good dentist who specialises in nervous patients, and I can be referred by them to the sedation clinic if they think it's necessary. Another question - how much work can they do in each trip? The HV said that if I am sedated then DH will need to stay home and look after babe that day and the next too.
any dentists out there!
