Hi all.
33 sessions of radiotherapy for thyroid cancer finished in June. I am 42.
Before starting I had hospital dental appointment to check if any of my teeth needs removing, etc.
Everything was fine, no removals.
I was given advice on dental hygiene moving forward.
And some of it seriously worried me.
I limit sugar intake a lot, but my morning coffee is my "me time". I have expensive coffee machine, that's how serious I am about my morning brew.
I like it with loads of milk, but I cannot force myself to stop using sugar.
Dentist told me I have to stop all sugars immediately, otherwise I will be in real trouble.
I have good oral hygiene, strong teeth, that come after my dad, he never seen a dentist in his life and had all teeth at the time of death and no problems with them.
I know to some that will be no issue, I understand.
However for me it feels like cancer took so much from me, and even that half an hour before work every morning, need to be spoiled as otherwise I will become toothless.
Will having 2 sugar in your coffee in the morning really cause me so much problems?
I would like to hear your stories,good or bad.
Thank you.
Izzy.
I still enjoy the honey my bees produce. I use Duraphat tooth paste twice or thrice daily, brush before breakfast, and have a fluoride varnish every three months. In nearly eight years I have no new caries. I lost a front tooth because a thirty year old crown failed but that’s nothing to do with eating sweet things.
I don’t often snack but when I do I rinse my mouth out with water and swish with a fluoride mouthwash.
PS
The idea behind brushing when you get up in the morning is to remove overnight plaque which the bacteria from breakfast would feast on.
Hi Izzy. There are some things in life that help make it enjoyable and are non negotiable in my opinion. Your coffee in the morning is one of those. If you maintain good oral hygiene I don't see there is any need to stop having your coffee. I have a compromised diet as I can no longer chew and I eat a lot of pureed food that has some sugar in it plus regular Fortisips. I make sure that I clean my teeth after every meal and complete a mouthwash with bicarb and salt in it. When I go out I take a bottle of water with me and go to the bathroom and wash out my mouth if I have had something to eat or drink. I have been doing this for the last 7 years and have not had any dental issues. I see my hygienist regularly and she keeps an eye on things for me. As long as your oral hygiene is good I say keep doing what you are doing.

Oh, I do it straightaway and just with warm water
I've got expert with those little orange interdental sticks too
Hi Izzy,
I was told quite emphatically to avoid sugar by the restorative dentist who said I needed 3 molars removed prior to my radiotherapy. I work on the idea that they probably know a bit more about the subject than I do and have seen the consequences of people ignoring their advice.
I can just about drink coffee without sugar but it's not so pleasurable, and tea without is vile.
I asked him whether sweeteners would be a better option and he replied yes that's much better. Consequently I stick to sweeteners now and am happy with that.
If you were 82 I'd say do what you like, but at 42 my advice would be to listen to the dentist and maybe try some different sweeteners and see if any of them are ok. Some I tried were unpleasant but I found Sucralose to be pretty good.
