How long does novocain last when you get injected with it at the dentist?

It depends on how much you are given. 1 injection usually takes about 2 hours to wear off. You may get some aching at the site of the injection. You may also drool a bit. I find a warm cloth helps reduce the swelling faster.

I can't tell you that, but if you go to the dentist they can. If you can handle a little pinch, than you can handle getting a cavity filled. The shot of novacain is fairly painful, but not extreme. Then let it work it's magic, and tell them if you can feel them drilling. It's really not that bad at all. I'm ashamed to say I have had four cavities filled!

If you have a problem with your tooth, it can very easily manifest itself as a headache, especially behind/around your eyes.  You should call the dentist and have the date moved up/closer so you can get it taken care of immediately.  A person should only be on antibiotics for 7 to 14 days.  After that, the bacteria become resistant to the medication, and this could very well be what has happened.  The bacteria that caused the abscess have most likely become resistant and are now migrating to other parts of you body.  Have the date moved closer, and also have your dentist put you on a more potent antibiotic.

Just stick it on the charger.  How long do you think it is going to last anyway?  The batteries will keep it going fine like that for 5 years.  \n\nWhat does it matter if it lasts a week or 10 mins when you only brush your teeth for 2 min?

your dentist can decide. i only had mine on for 11 months, but my friend had hers for 3 and 1/2 yrs. it depends on how much work needs to be done.

Depends on the size of the cavity.  Superficial (pin point) cavities require very little drilling and you should feel no pain whatsoever.  \n\nFor more severe caries (decay), you may want to have lidocaine injections to numb the nerve.  These can be uncomfortable and you may feel a slight burning sensation from the lido, but it will pass and it feels better than no anesthetic at all.  Trust me.\n\nYou may even have a dentist who uses lasers to remove decay.  From what I understand, there's no pain involved and no need for local anesthesia.\n\nSome dentists use other techniques to put you in the right state of mind but I've never personally come across this.\n\nIn the end, if you don't get the filling(s), the infection, abscess and pain you will ultimately experience will be far worse than anything a dentist will do to you.

Yes, call the dentist.  It is normal to have sensitivity with a temporary crown if the tooth has not previously had a root canal but you shouldn't be having a great deal of pain.  Also, if you had the crown done last week then that's 4 weeks it's taking for the permanent crown to come back in from the lab... that's insane... it generally takes no more than 2 weeks.

First of all, TAKE THE LOCAL ANESTHETIC!!! Second, you'll want to rinse your mouth out with a saline solution for about 48 hours post-"op". Put 1/4 teaspoon salt in 4 oz. warm water and swish your mouth out at least twice a day for two days. (Note: You don't have to use all 4 oz.--this is just the proper dilution ratio) This will help your gums to heal up a little faster and will help reduce any swelling that may occur. Also, take some Ibuprofen. This is a great pain reliever as well as an anti-pyuretic. (reduces swelling) Tylenol doesn't reduce any swelling.

getting a filling is really easy now a days. the numbing is easy and usually painless. on upper teeth the numbness lasts about 1-2 hours while the lower takes longer to go away. \n\nbasically, the dentist removes the cavity with a handpiece that sprays water- the assistant suctions the water out with a little vacumn type thing - your job is to stay open and be still and usually it takes less than 5 minutes to get the tooth ready for the filling material. \n\nsometimes there are little extra steps depending on how large the cavity is but again, it's nothing for you to be concerned over just stay open and be still so they can work fast!\n\nthe tooth doesn't feel different  and if it does such as you are biting on it before the other teeth- you need to let your office know so he can adjust the filling.

Not after a month has passed.  Go back to the dentist before it leads to further problems.

If you go to the pharmacy or supermarket there is a cool thing over with the oragel.  I can't remember the name of it, but it comes with a small glass jar, tweezers and little tiny cotton pieces.  This is especially helpful if you have a cavity hole and can stuff a piece in there.  This will make it go numb and give you a little rest.  I found by loading up on the ibuprophen, alternating between that stuff and oragel it bought me 2 weeks until I went to the doctors and got a prescription for vicodin to last until my next doctor's appointment (3 days later).\n\nCheck with your doctor and see if you can get a pain killer, but also make sure to get an antibiotic so the infection will start going down before you see the dentist, then if they need to do anything they won't have to worry about infection.  The infection going down will also help relieve the pain.  Good Luck

Hi there,\n\nHope this info helps.  From what I know, the amount of enamel that is shaved off really depends on your existing smile.  However, a good cosmetic dentist will only remove the smallest amount necessary and there are other dental procedures that require a lot more.  You'll most likely be given Novacain...just like any other standard dental procedure.  As far as waiting two weeks:  That's true.  Although sometimes it can take less, it just depends on who your dentist works with.  After your teeth are trimmed, the cosmetic dentist will have to make a mold of your existing smile and that will be sent to the lab....i'ts called a "wax up."  Each veneer is then customized based on that replica and sent back for the final fitting.  Depending on how extensive your case is, you may receive temporary veneers until your permanent veneers come back from the lab.  If you don't have temporaries put on, you can expect your teeth to feel a bit rough but they usually don't look that different, but not enough to feel embarassed about.  It's only two weeks, max.  As far as how they'll look after they're done.  Well, if you go to the right cosmetic dentist who understands your situation and what you're trying to improve, they'll look fantastic.  You can choose the shade of the teeth (some people don't want tic-tac white teeth) and also discuss the exact shape and size of each tooth.  You'll definitely want to have a consultation with a few COSMETIC dentists in your area as well.  I'm not sure where you're located but the website below is super helpful...you can learn about some dentists in your area and arrange a consultation...most of them are complimentary.  Good Luck!

Well it takes just 5 minutes. And its painless too. ( Unless you need root canal treatment if the cavity is very very deep)

That's right.\nAnother cause could be that there might have been inflammation around or near the site of injection/infiltration.\nInflammaion causes tissue acidity, and acid destroys some of the anesthetic. So it would have been rendered less effective.\n\nBut as the inflammation subsides in few days, the anes. will act.

OK, I had to have a HUGE filling a few months ago because I had a really big cavity that I'd ignored for a long time. To be honest, yes, it did hurt a bit getting it done, especially when the dentist drilled deep in the tooth, close to the nerve. \n\nBut when I saw the dentist then it was an emergency appointment just to fix that one tooth - he told me that I had a lot more cavities, but he couldn't do them because he was only for emergencies. He told me I should find another dentist to fill them ASAP as some of the cavities were fairly bad. Anyway, I ignored his advice and a couple of weeks ago needed to have a tooth extracted because it got so rotten.\n\nSo yes, getting deep cavities filled can be a bit painful, but it's certainly better than the alternative, which is leaving them to get so bad they need to be extracted. If you feel pain during the fillings, tell your dentist and he can give you more anaesthetic. And you won't even feel the needle if he needs to give you more, because your gum will be numb. Good luck!

You will be fine.  The worst part is holding your mouth open!\nYou will have a topical anesthetic placed on the gums to numb up the tissue so you wont feel the actual injection as much.  You may feel a pinch, but breathe deeply and focus on that not the injection.  After about 5 minutes you will be pretty numb.  The dentist will then take a handpiece with a bur and remove the decayed portion of the teeth.  Since you will have amalgam, or metal, fillings placed the technique is a bit different than the white fillings.  The dentist, or if legal in your state a dental assistant, will fill the hole where the cavity was with the material and carve the anatomy in the softened metal.  With silver fillings you shouldnt eat for a few hours to allow the metal to completley harden.  It is completly set after 24 hours.  The advantage of the metal is that in that time you are biting and your filling actually comforms to the bite better than the white fillings that are light cured and are set at the appointment.  Some times you have to go back for a bite adjustment with the white fillings because your bite isnt right and you can have soreness in the area.  The silver fillings dont usually have this problem.\nBad thing about the silver fillings is that they are not tooth colored and they are not bonded to the tooth, so over time the margin where the tooth meet the filling will break down and bacteria can leak into the area and cause a recurrent cavity.  In any case fillings arent meant to last forever and they will need to be replaced anyways.  By that time you can have a white filling placed if you want.\nOh and they dont taste like metal but if you bite onto metal like foil or even a fork, sometimes you will get a bit of a wierd sensation.  And dont worry about the mercury in the filling either, there are a lot of people out there that think it will cause all kinds of problems, it is safe.\nGood Luck, you will be fine!

I found a dentist just recently in midtown Manhattan, NYC who is really worth travelling to! He is really painless when it comes to administering novocaine, so I have no problems with him giving me as many shots as I need to ensure that I'm numb! Also to enhance the pain-free experience (can you see what my major concern is?) he also offers noise-cancelling headsets with meditative music. I'm past numb, I'm almost blissful!\nHis website is below.\nGood luck!
